UI: Clicking icons at bottom at random got me a book adding menu. This begins an 'auto scan' which never finishes on my huge filesystem before I kill the window. I hate auto-scanning media management. But i understand other people expect that. But could you disable that?
First-run would be most sensible to present a dialog asking user for the 'books' directory (which it can then scan and add to sqlite database). No auto-scan entire filesystem by default.
Ctrl-Backspace works ✓ which lets me get out and kill application. ✓ Great addition to Maemo-Leste.
