Documentation
Give readers two complementary ways to move through long documents. Thumbnails render every page as a small preview in a scrollable strip. Outline surfaces the document's table of contents (bookmarks) as a collapsible tree. Both panels sit in the same collapsible sidebar and can be shown independently.

What if my PDF has no bookmarks?
The outline panel hides itself automatically when the document has no embedded bookmarks. Thumbnails still work and become the default sidebar content.
Are thumbnails rendered upfront?
No — thumbnails are generated lazily as the panel scrolls into view, so even a 500-page document opens instantly without flooding the CPU.
