Yes, the keyboard layout on the Prime version could be greatly improved. It really can't be final until full touch menus are in place, so we can "increase" the number of keys available.

Make a list of all suggestions so I can put them in place. So far I switched to the Prime for daily use and it takes quite a bit of getting used to, versus the more straightforward keyboard of the 50g.

Also if you feel there needs to be more key associations for the 50g, let's start a post with a list, that gets updated so we can implement them all.
