"Take All" in chests? Why not. It could sure save some useless clicking.
"Take All" arround? I'd rather have the enemies have their inventories: instead of picking up a dropped item, you click on the enemy to bring up his inventory which should contain all the items he is supposed to carry.
If a skeleton carries an axe, I don't see why you shouldn't be able to pick it from the corpse after the battle.
I won't start a new thread for my humble suggestions so I'll add them now.
I'd want to see cloaks in Divinity 2. I suggested it for BD but it wasn't possible.
I would like to have a two-weapon-fighting skill. Sword and dagger, for example.
I doubt it's too difficult to program yet it makes the game more interesting.
