I would like to figure out how to replace the current keyboard with an improved version. The current thumb keyboard is good, but it could be better.

It would be kool to count the key presses for 5 minutes of typing to find the most used keys and making them larger. QWERTY is good and familiar, however in an embedded environment it might not be the best choice to use a strictly standard QWERTY layout.

Anyone want to help look into this?
