Inventory Management (moving stacks quickly)

Right now to create a specific number of stacked items you have to right-click to drop X amount of items, remove the remaining stack from your inventory (e.g. put it in a chest), then pick up the individual items off the ground.

Since Shift-click is used to move a full stack between inventory & storage, perhaps Ctrl-click can be used to move single amounts of the stack between inventory windows? This should pose no issue with desync since items are transferred the same way as with Shift-click.

Bonus idea: a button on inventory / storage windows that automatically stacks items that are not in full stacks with each other. This could have more logic too (sort alphabetically, etc.) but primarily should just clean up items that are not stacked efficiently.

Thank you for such a great game ^_^
