Please for the love of our carpal tunnels add a way to separate more than one item per click!

I'd include that under "move specific amounts of items." I just focused on stack splitting because I'm assuming it's simpler to do. Specific amounts would be preferable.

 

Playing lots and lots of minecraft. Stack splitting + being able to move individual pieces is much easier and faster than having a separate dialogue box (or whatever you call it) pop up. You can get just about any number combination fairly quickly.

 

I want to throw in a vote for a menu option of "never use lockpicks for doors". Chest are always more important.
