Since you changed the interface (version 10, I think), when you search for a note and click it, on your search bar, the mid bar disappears and the note becomes 2/3 of the screen. I don't understand this behaviour, but is not convenient. It used to show, in the mid bar, the notebook in which the note was contained —a lot more useful.
Is there a way fo switching this back to the old way? Can you make it possible? Or at least, how do I get back the mid bar easily? It just goes away, there's not even a shortcut or menu function to get it back.
