When I search for a book in my library on the iPad app, there's a little pop over that appears offering to search my entire library for what I typed in the library find box.
Usually it pops over exactly over the title of the book I need to open.
It usually delays and appears the moment I tap the title of the book, so my fingers tap the popover instead and run a search I didn't want.
This has been highly annoying. It either needs to be moved somewhere else on the screen, or give us the option to disable it. I don't need it at all.
