Takes the old BankIt and fixes the miniwindow for buttons. Originally, it was parented to the bank or guild bank based off which was open, however those no longer report their positions correctly and there isnt really a fix for that. So instead, I made the miniwindow its own separate draggable window that saves its location (per character) and added a resetmini command if you want to reset it.
Also fixed the mover getting stuck.
