I find it a bit ... exhausting, when I want to move items far up or down. It's slow and kinda clunky.

My suggestion is that by double clicking an item, it is added to the hands' inventory, and you can scroll normally without issue. The hand could potentially hold multiple items (but not too many to prevent people taking too much advantage of it, maybe 5?)

It'd make it a lot easier if I wanted to move multiple items up and down the farm.
