Keyboard style preview

[Cwpute]

I would have liked the app settings to allow me a quick preview of the keyboard settings i have set, because currently you're forced to switch apps and find a textbox to bring up your keyboard...
It would greatly help understand what is exactly changed when you modify your settings.

A floating button that brings up the keyboard on all settings screens would do i believe !

Don't know if it's a good idea, but alternatively, the keyboard could pop up for a few seconds after every change in its style, so as to briefly showcase the changes made.
