Button that sorts all keys and/or encoders

[sanderdatema]

This is a quality of life request, so no high priority at all. I'd love to be able to sort all the keys and encoders with a simple press of a button instead of dragging 300+ keys around.

I use pf.<aircraft/plugin>.<key_type>.<name> (pf for Passenger Flying, the name I use for my work) as a naming convention now, so sorting would help navigating all the keys a lot.
