Please add dark mode!

Looking around at these forums I see that development has pretty much halted on this, which is sad as it's a great and easy to use notation editor. But just wanted to say that this app really needs a dark mode. Probably going to have to switch to a different editor in the meantime because lack of dark mode is a deal breaker in 2021.

This would be nice indeed
