I think that the area were you chose your items should have all 4
category's, this is a smaller suggestion but I feel it would be
faster and that is the overall goal for the station!
(imagine the same as your item bag so you can easily find
items)

Add a all tab for people that like it how it currently is
No support. I have a ton of items and even I could quickly
and easily find things. They're sorted by categories. Having tabs
would make it more confusing I think because having to switch from
tab to tab if you're sending items from different item types.
No support from me. It's set up like the shop when you are selling
things. I find it easier to have everything in one place, instead
of the range of tabs, so it's actually quicker and easier for me
how it is now than if you added tabs to it.
