Like auto charge/repair I would like a stamina, magicka and health potion to be consumed. In that addon I want a selectable set for PvE and a set for dungeons, etc.
There already is a new addon "Well Eater" but it searches for the food, drink and potions and it doesn't have any sets.
I'm pretty certain that consuming a potion in combat is not possible for an addon and would be considered a violation of the TOS (botting) on top of that. Best it could do is select the correct potion and show a warning on screen that you need to press a key to drink it.
FcoStarveStop got food and potion reminders plus settings to remember the potion selected. In combination with addons like Greymind quickslot bar it works well. Auto potion usage is not possible as Siri already said, only selecting it and you get a reminder annex need to press the key manually.
