I want to suggest to at least release the spacebar.
Since its use is not intuitive (“take all” from a target inventory, but “drop item” in the personal inventory is colliding hard).
I would prefer it to be released, but implement a free configurable key to transfer items on mouseover betweens inventories instead (like user tiny suggested a few days ago).
I don’t know how many items I lost up yet because of this spacebar collision, when transferring between storage containers while my personal inventory was active and dropped the first item slot with every spacebar usage.
I wish you all a nice time.
