## Summary Adds support for browsing and downloading books from a Calibre-web server via OPDS. How it works 1. Configure server URL in Settings → Calibre Web URL (e.g., https://myserver.com:port I use Cloudflare tunnel to make my server accessible anywhere fwiw) 2. "Calibre Library" will now show on the the home screen 3. Browse the catalog - navigate through categories like "By Newest", "By Author", "By Series", etc. 4. Download books - select a book and press Confirm to download the EPUB to your device Navigation - Up/Down - Move through entries - Confirm - Open folder or download book - Back - Go to parent catalog, or exit to home if at root - Navigation entries show with > prefix, books show title and author - Button hints update dynamically ("Open" for folders, "Download" for books) Technical details - Fetches OPDS catalog from {server_url}/opds - Parses both navigation feeds (catalog links) and acquisition feeds (downloadable books) - Maintains navigation history stack for back navigation - Handles absolute paths in OPDS links correctly (e.g., /books/opds/navcatalog/...) - Downloads EPUBs directly to the SD card root Note The server URL should be typed to include https:// if the server requires it - HTTP→HTTPS redirects may cause SSL errors on ESP32. ## Additional Context * I also changed the home titles to use uppercase for each word and added a setting to change the size of the side margins --------- Co-authored-by: Dave Allie <dave@daveallie.com>
