Highlights & Notes
You can now highlight text and write notes directly inside your books. Select any passage in PDF or reflow mode, and the action pill gives you instant access to highlight, annotate, copy, look up, or share without breaking your reading flow.

Highlights come with a color picker so you can organise by colour, and notes open in a full bottom sheet with a comfortable writing area. Everything saves automatically.

Your Annotations, All in One Place
A dedicated Annotations screen lets you review everything you've highlighted and noted across your library. Filter by type, sort by position or date, and tap any entry to jump straight back to that moment in the book. The reader also has a side drawer showing all annotations for the current document.

Look Up & Copy
Two new quick actions sit in the selection pill: look up a word or phrase instantly or copy text to the clipboard.

Smoother Reading Experience
- Opening a book now feels fluid, with a shared element transition from your library cover
- Bottom sheets throughout the app have been redesigned with a floating style and spring animations
- The library loads noticeably faster thanks to cached thumbnails and prefetched voice avatars
- The return-to-sentence arrow only appears when it's actually needed, keeping the reader cleaner

Deep Link Improvements
Gift, referral, and redeem links are handled more reliably. The app now also responds to /open links by navigating directly to the home screen. 1.0.25 May 11 Highlights & Notes
