@nimakro Once it is polished it will go into TornadoFX Core. I'm investigating whether it could be a more general layout instead of a Keyboard layout as well, so it will be more usable. One could argue (and one would be correct 😁) that a Keyboard layout is a bit of an outsider, but with the right listeners it can be used for accepting input for touch screens etc, for example as a number pad embedded in a View.
