✨ Key Features
Visual Reading Status: Instantly know the status of any work on search results, tag pages, or bookmarks.
Mark a work as Fully Read (e.g., Purple).
Mark a work as In Progress/Partial Read (e.g., Blue/Green).
Mark a work as Do Not Read (e.g., Red/Hidden).
Persistent Chapter Tracking: On multi-chapter works, the extension saves the exact chapter and date you stopped reading. You'll never start from the beginning again!
Reading Filter: Use the Active Reading Filter to hide works you've already read or marked "Do Not Read," making your search results short and relevant.
Custom Color Schemes: Personalize your visual markers by choosing your favorite color for each status directly in the Synchronization Settings.

- The bookmarking feature is excellent. However, after installing the extension, pagination disappears on both search results pages and bookmark pages. There’s no longer an option to jump to a specific page—you can only keep scrolling with auto-loading. As a result, you’re effectively limited to browsing just the first few pages of results. I’ve encountered this issue on both Edge PC and Android. I’m not sure how it performs on Chrome, so it might be a compatibility issue. I’ve also tried the JSON sync feature, and it works perfectly between my phone and computer—really impressed with that. Just hoping the dev can work some magic and bring back pagination!

- Perfect. This is exactly what I was looking for. It's possible to reread works I've already read.

- I only downloaded this for the mark read button. The stats and whatnot are neat and work well, but I have my own system for tracking so I wont use those features. It does what I need very well, so 5 stars. The only thing I dislike is that for some reason this removes the pages feature, and makes search results an infinite scroll, which is a significantly worse way to view content IMO. This would be an actual perfect extension to me if this was either removed or able to be disabled in options. I almost gave 4 stars because of this, but as there are no reviews I didn't want a perfectly fine extension to have a lower rating than necessary. I know that was a lot of complaining but I overall do really love this, and I will continue to use it!!
