Curl / slide turns
Curl animation or classic slide. Switch anytime; your choice is remembered.

Personal bookmarks
Press B on any page. A red ribbon appears; open the panel to jump or manage marks.

Built-in PDF outline
If the PDF has a table of contents, open the side panel and jump to chapters with nested levels.
🖼
Minimal immersive UI
No toolbar by default; move to the top edge to reveal controls. Paper margins around the page like a book on a desk.
