v1.1.11

Gallery: new Shown/Ignored tabs — long-press a thumbnail to move it between them (add back images the relevance filter set aside, e.g. a map; or ignore ones you don't want). Empty state offers 'Review filtered-out' when everything was filtered. Per-image rotation now persists immediately (survives an unclean shutdown). Scan cache now lives in the book's .sdr sidecar so it travels with the book between devices.
