Keypress to initiate search by letter ?
This may or may not be possible with the gamepad binding option but I haven't unlocked it yet.
It would be great if a alphabet carousel could pop up on key press to jump to games beginning with that letter.
This is an idea borne of using riivive theme which by default only shows three items on screen at once and you have to scroll for aeons to find anything. Or dig into search menu.
