Opener learner
just a quick prototype of something i thought would be useful in your overlay. no worries if you dont want this, or dont want this implementation.
ive been learning new classes and something i wanted was to be able to learn the opener and practice it easily, and your overlay already stores actions used and formats them nicely in the rotation section
i added a way to save a specific rotation as an opener, and compare against the current rotation

heres a screenshot of doing a wrong opener, and the button to save an opener:

this is great! I've been busy recently but I'll get around to looking over and adding this to the main repo soon.
