Agree, need more slots, and not just for uniforms, but to also be able to switch profiles, have them linked to ship builds, i.e, player and ship pve build, then switch to player/ship pvp build with one click of the mouse.
Now that I have the option to wear the flap down on the WoK uniform, I am really hurting for another uniform slot....
I'll second this.
I've got the TOS, DS9, and TWOK uniforms unlocked, but I can only have two of them "ready to go". If I had two more slots I could have the open flap and my "Grand Admiral White" DS9 uniform on hand. :/
