• Spine shelves now show every book. Home, folders and search shown as spines stopped at 5,000 books before.
• A theme of your own can now be just a wallpaper: make a folder in koreader/settings/bookshelf/ornaments, put a folder called theme inside it, and put your wallpaper.png in that. It shows in the Theme library under the folder's name, with no theme.json or ornaments needed. Optional wallpaper.dark.png, wallpaper.full.png and wallpaper.full.dark.png cover dark mode and full screen shelves.
