[AColobus]

Oh hey, the signs are back now after a reboot. The Kobo is now playing other silly tricks instead; I'll update if necessary.

EDIT: I'm (or rather, Kobo are) an idiot. The plus and minus signs only appear when the Kobo is plugged in, even though there is no reason you would only want to plan and curate your collection for device synch when the Kobo is plugged in - and in fact, doing it beforehand and then running a synch will probably be more efficient than fighting to do so during live synch with its attendant hangs.

I am now performing a second factory reset. The original one plus bizarro synch attempt left me with the first page of each chapter of the five random books it consented to load, and a login screen loop whenever I tried to use the reader with the app again. Hoping this will fix it...
