New
- Hardware page-turn buttons now drive Bookshelf pagination on devices that have them (Kindle Oasis/Voyage, Kobo Forma/Libra, Bigme/Boox/etc. Android e-ink with key-mapped volume keys). At the last page of a tab, pressing forward cycles to the next tab; at the first page of a drill-down (folder/series/etc.), pressing back goes up a level. Mirrors the existing swipe-to-paginate behaviour.
Possibly also fixes
- KOReader could become unresponsive (ANR on Android) when pressing hardware page buttons with Bookshelf as the home screen. We can't reproduce on hand to confirm, but the new key bindings keep these events on Bookshelf rather than letting them fall through to the hidden FileManager underneath.
