[Suggestion] Shortcut for changing active skill sets :D

Hello kind developers,

You might didn't expect that some or few players learned more than 4 active skills, but
just like you make equipment quick loadout button, how about you make another one for active skills?
and maybe put the shortcut on HUD :P, (it seems like you already made skills cooldowns remains unchanged everytime we changed skills, so why not adding this function :D)

OR, remove the limit of 4 active skills, lol

thank you very much, kind developers!
