This is a very minor issue, but I thought it worth mentioning. Whenever I attempt to rotate placed drawers using a tool designed to do that, the results are not exactly what one would expect:

• If the mouse button is pressed down for more than the briefest fraction of a second, the drawers will rotate 180 degrees several times.
• Holding the button slightly longer than that causes the tool to be placed inside the drawer (if it is empty).
• In the case of the Crescent Hammer from Thermal Foundation, this has led a few times to a "phantom tool" where the tool doesn't appear to be in the player's inventory or in the drawer, but clicking on an apparently empty slot in the inventory will eventually cause the tool to appear.

I've tested this with both the Engineering Hammer from Immersive Engineering and the Crescent Hammer from Thermal Foundation (those are the only two rotating tools I have on my server).

I assume this is due to some sort of conflict between the way Storage Drawers handles mouse clicks and the vanilla way they are handled. Like I said, it's nowhere near a gamebreaker bug, but it's an annoyance when trying to place items.
