I generally use Bandit UI to tweak my UI. Everything works fine, however there remains one slot on screen that is a mystery. I marked it on the screenshot:
This slot is not a quickslot, it seems. It always remains empty. The keybinding associated with it is that of 'Command pet', which is used for summoned combat pets. If I unbind this keybinding, it will no longer show under said slot. But a pet never shows in there, nor can I drag one unto it...
Does anyone know which setting / addon ? does this and how to turn it off?
Thanks for your help!
