Might be a stupid question but what's supposed to happen when I hit "tweaks"?
When I hit it, my Kobo resets. Is there anything I have to install or something else that I have missed somehow?
Also the bookshelves "vanish" once I entered one of them until I go to the homescreen and back to library again. But maybe that's normal, too, like having to go to the library once before getting to see the extras in the menue?
