quick JDI suggestion: make actions right clickable in the palette. It's counterintuitive that you have to use the flyout menu to change shortcuts or change settings to actions and sets. those options should also be accessible with a right click.
I just played around with it some more and found that you can at least double click to get into the settings and I'm also aware that there is a little trash can on the bottom of the palette so I guess most things can be done without accessing the flyout menu. however I still find it unintuitive that I can't right click them.
