Time to go to bed...
I've added shift button in alphanumeric and changed its behaviour also in qwerty. Behaviour is changed also for additional layouts in qwerty.
More big font for button: done
Icons are now taken from file, so easy customization is possible

next step are:
new layout in qwerty for non latin language
symbol/smile layout in alphanumeric
enable customization for font color on buttons
improve vibration feedback

If you guys think that I'm losing something please speak
