The current layout of the player arsenal tab is not "friendly" when changing gear or equipping new load outs or looking for specific items quickly.
With the addition of several new items, some of the tabs are becoming over loaded with items - and usually the useful ones you want to look at require the player to scroll through "stuff".

Here's the proposal.

Split "Usable" tab into: Upgrade Slots, Usable and Boxes.

Reorganize tabs from Top --> Bottom:
- Sword, Hand Gun, Bomb, (add a spacer), Helmet, Armor, Shield, Trinket (add a spacer), Costume, Accessories (add a spacer)
- Recipes, Materials, Tokens, (add a spacer), Upgrade Slots, Usable, Boxes, Keys, (add a spacer), Minerals, Artifacts

The advantage of these two changes:

- puts all the equip type items together at the top of the arsenal
- puts costumes and accessories together as they are both cosmetic in sense of game play
- puts all of the crafting type items together
- upgrade slots are currently at the bottom of the usable tab, not user friendly. Giving them their own tab makes them easy to check in terms of when they will expire and would make it easy to find them on the AH.
- love or hate boxes, giving them their own tab makes them easy to find in the inventory - bigger perk really for searching on AH

When I refer to adding a spacer, this would be a blank tab, about 1/2 height of the current tab, just to help further separate the current layout, make it a little quicker to navigate.
