Ok, I have a couple of suggestions.

When using the controller page (up, down, home, full screen, etc) I would love to have some kind of push feedback, like when typing in the n9 keyboard, so I can press those buttons without looking and have some kind of response feedback.

Another suggestion I have is to support long presses on those buttons, so I can push down while on a list and the remote will keep scrolling down while the button is pressed.

Hope this makes sense.
