I found this UI on the forums, and i've seen movies on youtube, the thing is it lets you choose stuff on the UI, like Sizes, Where you want your spells to be, size of the spells, and such But the cool thing was, You could open a thing, And you could use keybindings by that, just pressing at a ''Change Keys'' or something, you pressed at a bar, and then lets say F and it became F

Help me find this.
