Why are the empty directions not filled with numbers/symbols etc? - eviltoast

Yeah, of course not all symbols will fit, but wouldn’t it be better to minimize the context switching? Numbers for example are used very often, I really don’t see why I have to go to a different page to be able to type them.

Corollary, is it possible to easily create a custom layout for personal use? Or do you have to check out the code and build yourself etc?
