The closet in the corner is so far rather useless, aside from imprisoning EN when he gets annoying. It's lacking many of the things you usually find in department closets. Namely, I think it should contain
Spare Science Headsets. Otherwise, roboticists that lose theirs or are reassigned need to break into scichem or something to get them from there.
Backpacks and/or Dufflebags. Same reason as above, plus I like to put the surgery tools in containers rather than having them clutter things up.
It shouldn't be such a big change and bring the closet in line with other department closets, which always contain stuff like department headsets. Plus, I've never seen anyone wear the hats in that closet, or anything else from it aside from the HUD.
