When BookInfo is opened for a book with no existing cache, epub.load(true, true) triggers a 1-2s full parse. Show a "Loading..." popup with progress bar so the device doesn't appear frozen. Popup only appears on the fallback path — cached books load silently. Same pattern for XTC books. Made-with: Cursor

BookInfo Loading Popup for Unopened Books
Date: 2026-03-09 Task: Show a progress popup when BookInfo needs to parse an unopened book
Changes Made
BookInfoActivity.cpp
Added a "Loading..." progress popup with progress bar to onEnter() when the book cache doesn't exist and a full parse is required:
- EPUB branch:
epub.load(false, true)is tried first (fast, cache-only). If it fails,GUI.drawPopup(tr(STR_LOADING))is shown at 10%,epub.load(true, true)runs (slow full parse), progress updates to 50%, thumbnail generation runs, then progress hits 100%. - XTC branch: Checks
Storage.exists(xtc.getCachePath())beforextc.load(). If cache directory is missing, shows the same popup pattern around load + thumbnail generation. - For books with existing cache, no popup is shown — the fast path completes silently.
Build Result
Build succeeded — 0 errors, 0 linter warnings. RAM: 30.3%, Flash: 95.7%.
Follow-up
- Test on device: open BookInfo for a book that has never been opened, verify popup appears
- Verify no popup appears for books that have been previously opened/cached
