I'm also hoping for everything you mentioned, as well as a context menu on inventory items, so I can opt to either:
1. send the item to another group member by clicking on the portrait.
2. select the item for crafting with another item, so I don't have to drag & drop.
3. equip the item.
4. split a stack (as an alternative to shift-clicking).
5. drop the item.
Also, is the key-binding menu broken? All I get are general binds and I can't figure a way to get to the other functions.
