while it requires 2 hands, theres a shift+click which seems to work pretty well.
one of the cool things i like is the “press spacebar” to take all, especially when looking at a characters inventory or a chest, but i cant seem to find a way to re-map the key (or remove) the Drop current item stack (using spacebar)
basically what tends to happen in the heat of combat (or in the aftermath), is i open a container (chest or person), and press space, only to realise that the spacebar got triggered twice, and ive not only picked up the container items, but suddenly have also dropped “something” from my inventory, onto the floor in a loot sack container - potentially repeatable
