Inventory auto sort and stack?

[kram]

Ah, that's why. When you drag them they go to where you drag them. Simply right click on the item you want to deposit and select the top option (usually doesn't even require moving your mouse if the menu is in it's proper position and not pushed up by being too close to the bottom of the screen). I've never dragged things into my retainer inventory, I always just do a rapid right click left click combo to send them to their spot, then sort the retainer inventory after if needed.

Ah that's why. I will check again later. Thanks
