"Move Up" only moves 1 slot above, it's bothersome if your Pokemon is low on the list.
The ideal should be a option to quickly swap your Pokemon on the overworld, maybe new shortcut keys or a new option like the one I said in the OP.
Please put a "Switch to First" option or something akin to that here, it's a pain to play with joystick otherwise because you need to keep resorting to use mouse to switch mons around, which kinda defeats the point of joystick support in the first place.
