Super glad you've found it useful! This is an interesting idea,but I may end up solving this in a different way. I am hoping to be able to flesh out custom actions to be further defined.for example you could set a custom action to be "walk", which would be used if moving under x speed. Or set it to turning, double jump, dash, etc.
This won't be in this update, but I'll start looking into this for potentially the next update after that.
