Supporting Sudokus

[meikpiep]

Hey, because your app's layout is very similar to sudoku, any plan's on adding sudoku game in gauguin or make another app? I don't know much, but maybe it would be easier because only the functionality is different but all layout of app will be same.
I use libresudoku but its's input layout functionality is not good as yours (buttons are small and it don't use gestures). Thought i created a issue on their's repo today, maintainer's not very active on opened issues.
