We had in the past a little menu-bar. Now we press or hold the buttons on the site for open apps. It is of course personal, but I would like the same as a button on the bottom or side if my screen. I'm afraid the over time those plastic buttons will work worse.

futhermore, I think I mentioned this before, but when I look at pictures stored on the SD-card I can't let's say scroll to them. It would be a great joy to be able just to go foreward or backwards, while leaving them on the card.
someone gave me ones a hint, but I can't find that anymore and I think I had to move them first to the internal storage what I don't want.
