K5 Suggestion for a virtual keyboard hack (K5, KPW)

I was thinking: there are some apps for K5 and KPW in which keyboard covers the text form where you are typing (usually when the form is in the bottom half of the screen). Skipstone browser is an example.

I thought two possible solution for this, but don't know if they are doable and how much effort require.

FIRST IDEA
Add two little buttons to the keyboard (maybe nearby the keys A and L in the QWERTY one): one, to put the keyboard at the top of the screen, the other to hide the keyboard.

SECOND IDEA
I don't like the bar over the keyboard that suggest words completions (it's a bit slow to be useful, to me). Could it be hacked to display the text typed, instead of them? For example, sending every character pressed on the keyboard directly on that row? In this case, the backspace would also erase the letters in the stack to keep it synced with the form.
Obviously, there would be a problem when the user changes focus and the stack becomes unsynced with the text, but could be partially solved by cleaning the bar at every click away from the keyboard (= pointer repositioning).

THIRD IDEA ("better then nothing")
Make at least an hack to get rid of the aforementioned bar xD It would free some useful pixels...
