Description of the feature

Instead of a regular right-click with an empty hand to remove the upgrade, require a sneak-right-click with empty hand. This would prevent accidental removal of upgrades, especially when trying to dump multiple stacks from inventory.

Also, double-right-click with an empty hand should attempt to fill all identical items from inventory into the drawer. As it stands, I add one stack and then remove the upgrade.

How does it make the mod better?

This would streamline adding stacks in bulk and eliminate the accidental removal of upgrades.
