Feature, performance, and bug-fix release:
- Two-Page (Book) View: New toolbar toggle (Ctrl+Shift+B) lays pages side-by-side like an open book — the cover sits alone on the right, then pages pair up (2-3, 4-5, …). Scrolling stays continuous.
- Fit to Width: New toolbar button (Ctrl+0) sizes the page — or the whole spread in book view — to fill the window width. Accounts for rotated pages.
- Much faster opening of large, graphics-heavy PDFs: the first page appears almost immediately instead of waiting for the whole document, and overall load time is substantially reduced.
- Smoother scrolling through image-laden PDFs, with no more stutter.
- Lazy sidebar thumbnails: thumbnails render as they scroll into view rather than all at once on open, so long documents open faster and use less memory.
- Fixed text-markup alignment issues: highlights bleeding across columns in multi-column layouts, markup sitting too high or low on PDFs with non-standard font metrics, and markup landing shifted on PDFs re-saved by other tools.
- Fixed highlights jumping to the previous line when a selection started mid-paragraph.
- Fixed being unable to select text with the arrow tool first and then apply highlight/underline/strikethrough on certain PDFs.
- Fixed pages stopping rendering partway through large documents on Windows.
- Offline OCR on Windows: the Tesseract engine and language data are now bundled into the Windows build.
