Ok, I'll see what I can do for the layout, at least for QWERTY and AZERTY
Here's my feedback: I would personally prefer a less blocky keyboard. What I mean by that is that for example, your A and Q keys are exactly on top of each other, as compared to the regular Android keyboard where they are space a bit differently (closer to a real keyboard).
Strange.. for me, the first key is printed as soon as the second key is pressed. Maybe I can change the behavior for a future version if people ask for this.
When I hold down a key, and press another key, neither of them are printed til the screen until I release the second key. Would it be possible to print the first to the screen as soon as it is pressed, and same with the second?
