Hey I have an idea for he Key Bindings section in bar mod.
You already show all the slots for Group 1, maybe rather than have a scroll bar on the side, with all the other groups below, maybe you could do one of 2 things.
either only Show the key bindings for the group selected under Bar Options only, and change the list with the same selector. Or, maybe you could use tabs, or a row of buttons to select what group you want to edit bindings for.
Just an idea
I do like that you can close a group BTW! nice.
(I actually rarely bind new keys because nobody that I know of has come up with a clear way of letting you know what keys are already in use, and for what, and a way to maybe print out a key chart)
