i would like to see an add-on that simplifies warlock demon training. maybe something that hides already known grimoires and ones that can't be learned yet. i think this should be in the default blizzard ui. buying demon spells is more time consuming than it should be. i thought someone would have done a simple add-on like this by now, but i'm having trouble finding one on any of the mod sites, so i thought i would come here and make a request. anyone else think this could be a helpful little add-on?
