Frequently Asked Questions
- No bookmarks — is the file broken?
- Almost certainly not. Most generators skip outlines unless asked. The content is unaffected.
- Why do some entries lack pages?
- Their destinations use forms this reader cannot resolve (named actions, embedded gotos). The titles still display.
- Can I edit or add bookmarks?
- Not with this viewer — it reads only. Dedicated editors handle bookmark surgery.
- Max entries?
- 500 capped for performance. Large manuals show first 500 in order.
- Scanned PDFs?
- No outline expected. OCR does not create bookmarks — need authoring tool.
- Private?
- Yes. Outline walk stays local.
