Problem: It is a pain to have to keep an eye on your food and potion buffs and constantly reapply them. EQ2 has a very nice system to handle this.
There should be two extra slots on the Hero page that you can drop stacks of Food and Potions into. When there are stacks of items in these slots, the system would automatically consume them to provide the respective buffs.
IE: you drop of a stack (25) of meatballs in to the food slot. The game immediately consumes 1 so you now have a stack of 24 and the meatball buff. 30 minutes later, the meatball buff expires and the system automatically consumes another one, leaving 23 meatballs.
To stop the auto consume, simply move the stack back into your inventory.
