I was thinking of getting a Tourbox Lite but I think I would like just a few more buttons without getting into layers of macros. I found a new workflow I like in which shortcuts beyond brush size changing and undo/redo would be handy to have. I'm looking into getting a macro keypad like a Razer Tartarus v2 or a secondhand Logitech G13. Too bad there's not many options for one of these that have a joystick.
