I often use CTRL+Drag to pick up something like a corpse and drag it into my cart.
When I pick up a pile of items, for example foraged items or archaeology fragments and CTRL+Drag the item pile to my cart, always exactly 2 items are left on the ground.
Because of this I have to use CTRL+Drag three times to pick up all of the items.
With archaeology fragments these occupy the same position but are large enough to pickup easily, however, with small foraged items such as acorns or eggs, it's a lot more fiddly.
It would be great if CTRL+Drag picked up the whole pile of items, and did not leave two items on the ground.
