## What's New in v4.1.1?
Version 4.1.1 introduces a smarter way to capture images that might be embedded directly within post descriptions, enhancing content discovery.
### "Scan Content for Images" Feature
- **Enhanced Image Discovery:** A new checkbox, "**Scan Content for Images**," has been added to the UI (grouped with "Download Thumbnails Only" and "Compress Large Images").
- **How it Works:**
- When enabled, the downloader scans the HTML content of posts (e.g., the description area).
- It looks for images embedded via HTML `
` tags or as direct absolute URL links (e.g., `https://.../image.png`).
- It intelligently resolves relative image paths found in `
` tags (like `/data/image.jpg`) into full, downloadable URLs.
- This is particularly useful for capturing images that are part of the post's narrative but not formally listed in the API's file or attachment sections.
- **Default State:** This option is **unchecked by default**.
- **Interaction with "Download Thumbnails Only":**
- If you check "Download Thumbnails Only":
- The "Scan Content for Images" checkbox will **automatically become checked and disabled** (locked).
- In this combined mode, the downloader will **only download images found by the content scan**. API-listed thumbnails will be ignored, prioritizing images from the post's body.
- If you uncheck "Download Thumbnails Only":
- The "Scan Content for Images" checkbox will become **enabled again and revert to being unchecked**. You can then manually enable it if you wish to scan content without being in thumbnail-only mode.
This feature ensures a more comprehensive download experience, especially for posts where images are integrated directly into the text.

## Previous Update: What's New in v4.0.1?
Version 4.0.1 focuses on enhancing access to content and providing even smarter organization:
### Cookie Management
- **Access Content:** Seamlessly download from Kemono/Coomer as if you were logged in by using your browser's cookies.
- **Flexible Input:**
- Directly paste your cookie string (e.g., `name1=value1; name2=value2`).
- Browse and load cookies from a `cookies.txt` file (Netscape format).
- Automatic fallback to a `cookies.txt` file in the application directory if "Use Cookie" is enabled and no other source is specified.
- **Easy Activation:** A simple "Use Cookie" checkbox in the UI controls this feature.
- *Important Note: Cookie settings (text, file path, and enabled state) are configured per session and are not saved when the application is closed. You will need to re-apply them on each launch if needed.*

### Advanced `Known.txt` and Character Filtering
The `Known.txt` system has been revamped for improved performance and stability. The previous method of handling known names could become resource-intensive with large lists, potentially leading to application slowdowns or crashes. This new, streamlined system offers more direct control and robust organization.
The `Known.txt` file and the "Filter by Character(s)" input field work together to provide powerful and flexible content organization. The `Known.txt` file itself has a straightforward syntax, while the UI input allows for more complex session-specific grouping and alias definitions that can then be added to `Known.txt`.
**1. `Known.txt` File Syntax (Located in App Directory):**
`Known.txt` stores your persistent list of characters, series, or keywords for folder organization. Each line is an entry:
- **Simple Entries:**
- A line like `My Awesome Series` or `Nami`.
- **Behavior:** Content matching this term will be saved into a folder named "My Awesome Series" or "Nami" respectively (if "Separate Folders" is enabled).
**2. "Filter by Character(s)" UI Input Field:**
This field allows for dynamic filtering for the current download session and provides options for how new entries are added to `Known.txt`.
- **Standard Names:**
- Input: `Nami, Robin`
- Session Behavior: Filters for "Nami" OR "Robin". If "Separate Folders" is on, creates folders "Nami" and "Robin".
- `Known.txt` Addition: If "Nami" is new and selected for addition in the confirmation dialog, it's added as `Nami` on a new line in `Known.txt`.
- **Grouped Aliases for a Single Character (using `(...)~` syntax):**
- Input: `(Boa, Hancock)~`
- Meaning: "Boa" and "Hancock" are different names/aliases for the *same character*. The names are listed within parentheses separated by commas (e.g., `name1, alias1, alias2`), and the entire group is followed by a `~` symbol. This is useful when a creator uses different names for the same character.
- Session Behavior: Filters for "Boa" OR "Hancock". If "Separate Folders" is on, creates a single folder named "Boa Hancock".
- `Known.txt` Addition: If this group is new and selected for addition, it's added to `Known.txt` as a grouped alias entry, typically `(Boa Hancock)`. The first name in the `Known.txt` entry (e.g., "Boa Hancock") becomes the primary folder name.
- **Combined Folder for Distinct Characters (using `(...)` syntax):**
- Input: `(Vivi, Uta)`
- Meaning: "Vivi" and "Uta" are *distinct characters*, but for this download session, their content should be grouped into a single folder. The names are listed within parentheses separated by commas. This is useful for grouping art of less frequent characters without creating many small individual folders.
- Session Behavior: Filters for "Vivi" OR "Uta". If "Separate Folders" is on, creates a single folder named "Vivi Uta".
- `Known.txt` Addition: If this "combined group" is new and selected for addition, "Vivi" and "Uta" are added to `Known.txt` as *separate, individual simple entries* on new lines:
```
Vivi
Uta
```
The combined folder "Vivi Uta" is a session-only convenience; `Known.txt` stores them as distinct entities for future individual use.
**3. Interaction with `Known.txt`:**
- **Adding New Names from Filters:** When you use the "Filter by Character(s)" input, if any names or groups are new (not already in `Known.txt`), a dialog will appear after you start the download. This dialog allows you to select which of these new names/groups should be added to `Known.txt`, formatted according to the rules described above.
- **Intelligent Fallback:** If "Separate Folders by Name/Title" is active, and content doesn't match the "Filter by Character(s)" UI input, the downloader consults your `Known.txt` file for folder naming.
- **Direct Management:** You can add simple entries directly to `Known.txt` using the list and "Add" button in the UI's `Known.txt` management section. For creating or modifying complex grouped alias entries directly in the file, or for bulk edits, click the "Open Known.txt" button. The application reloads `Known.txt` on startup or before a download process begins.
- **Using Known Names to Populate Filters (via "Add to Filter" Button):**
- Next to the "Add" button in the `Known.txt` management section, a "⤵️ Add to Filter" button provides a quick way to use your existing known names.
- Clicking this opens a popup window displaying all entries from your `Known.txt` file, each with a checkbox.
- The popup includes:
- A search bar to quickly filter the list of names.
- "Select All" and "Deselect All" buttons for convenience.
- After selecting the desired names, click "Add Selected".
- The chosen names will be inserted into the "Filter by Character(s)" input field.
- **Important Formatting:** If a selected entry from `Known.txt` is a group (e.g., originally `(Boa Hancock)` in `Known.txt`, which implies aliases "Boa" and "Hancock"), it will be added to the filter field as `(Boa, Hancock)~`. Simple names are added as-is.

## What's in v3.5.0? (Previous Update)
This version brought significant enhancements to manga/comic downloading, filtering capabilities, and user experience:
### Enhanced Manga/Comic Mode
- **Optional Filename Prefix:**
- When using the "Date Based" or "Original File Name" manga styles, an optional prefix can be specified in the UI.
- This prefix will be prepended to each filename generated by these styles.
- **Example (Date Based):** If prefix is `MySeries_`, files become `MySeries_001.jpg`, `MySeries_002.png`, etc.
- **Example (Original File Name):** If prefix is `Comic_Vol1_`, an original file `page_01.jpg` becomes `Comic_Vol1_page_01.jpg`.
- This input field appears automatically when either of these two manga naming styles is selected.
- **New "Date Based" Filename Style:**
- Perfect for truly sequential content! Files are named numerically (e.g., `001.jpg`, `002.jpg`, `003.ext`...) across an *entire creator's feed*, strictly following post publication order.
- **Smart Numbering:** Automatically resumes from the highest existing number found in the series folder (and subfolders, if "Subfolder per Post" is enabled).
- **Guaranteed Order:** Disables multi-threading for post processing to ensure sequential accuracy.
- Works alongside the existing "Post Title" and "Original File Name" styles.
- **New "Title+G.Num (Post Title + Global Numbering)" Filename Style:**
- Ideal for series where you want each file to be prefixed by its post title but still maintain a global sequential number across all posts from a single download session.
- **Naming Convention:** Files are named using the cleaned post title as a prefix, followed by an underscore and a globally incrementing number (e.g., `Post Title_001.ext`, `Post Title_002.ext`).
- **Example:**
- Post "Chapter 1: The Adventure Begins" (contains 2 files: `imageA.jpg`, `imageB.png`) -> `Chapter 1 The Adventure Begins_001.jpg`, `Chapter 1 The Adventure Begins_002.png`
- Next Post "Chapter 2: New Friends" (contains 1 file: `cover.jpg`) -> `Chapter 2 New Friends_003.jpg`
- **Sequential Integrity:** Multithreading for post processing is automatically disabled when this style is selected to ensure the global numbering is strictly sequential.
---
### "Remove Words from Filename" Feature
- Specify comma-separated words or phrases (case-insensitive) that will be automatically removed from filenames.
- Example: `patreon, [HD], _final` transforms `AwesomeArt_patreon` `Hinata_Hd` into `AwesomeArt.jpg` `Hinata.jpg`.
---
### New "Only Archives" File Filter Mode
- Exclusively downloads `.zip` and `.rar` files.
- Automatically disables conflicting options like "Skip .zip/.rar" and external link logging.
---
### Improved Character Filter Scope - "Comments (Beta)"
- **File-First Check:** Prioritizes matching filenames before checking post comments for character names.
- **Comment Fallback:** Only checks comments if no filename match is found, reducing unnecessary API calls.
---
### Refined "Missed Character Log"
- Displays a capitalized, alphabetized list of key terms from skipped post titles.
- Makes it easier to spot patterns or characters that might be unintentionally excluded.
---
### Enhanced Multi-part Download Progress
- Granular visibility into active chunk downloads and combined speed for large files.
---
### Updated Onboarding Tour
- Improved guide for new users, covering v4.0.0 features and existing core functions.
---
### Robust Configuration Path

---
### Smart Filtering
- **Character Name Filtering:**
- Use `Tifa, Aerith` or group `(Boa, Hancock)` → folder `Boa Hancock`
- Flexible input for current session and for adding to `Known.txt`.
- Examples:
- `Nami` (simple character)
- `(Boa Hancock)~` (aliases for one character, session folder "Boa Hancock", adds `(Boa Hancock)` to `Known.txt`)
- `(Vivi, Uta)` (distinct characters, session folder "Vivi Uta", adds `Vivi` and `Uta` separately to `Known.txt`)
- A "⤵️ Add to Filter" button (near the `Known.txt` management UI) allows you to quickly populate this field by selecting from your existing `Known.txt` entries via a popup with search and checkbox selection.
- See "Advanced `Known.txt` and Character Filtering" for full details.
- **Filter Scopes:**
- `Files`
- `Title`
- `Both (Title then Files)`
- `Comments (Beta - Files first)`
- **Skip with Words:**
- Exclude with `WIP, sketch, preview`
- **Skip Scopes:**
- `Files`
- `Posts`
- `Both (Posts then Files)`
- **File Type Filters:**

- **Scan Content for Images (New in v4.1.1):**
- A UI option to scan the HTML content of posts for embedded image URLs (from `
` tags or direct links).
- Resolves relative paths and helps capture images not listed in the API's formal attachments.
- See the "What's New in v4.1.1?" section for a comprehensive explanation.

- It's primarily used as an intelligent fallback for folder creation when "Separate Folders by Name/Title" is enabled.
- **Syntax:**
- Simple entries: `My Favorite Series` (creates folder "My Favorite Series", matches "My Favorite Series").
- Grouped entries: `(Desired Folder Name, alias1, alias2)` (creates folder "Desired Folder Name"; matches "Desired Folder Name", "alias1", or "alias2").
- **Settings Stored in App Directory**
- **Editable Within GUI**
