My suggestion is pretty much what the title says.
I really wish there was a search function for my cargo bays as I have 3 now and they are filled up with crafting materials, schematics, and gear. It gets really difficult searching for my items over and over again manually when I need to withdraw materials to sell on the GTN and such.
Even with it organized things could so much faster I could just type in the name of what I want to withdraw and it lights up with the other items darkened or something to make it easy to pick out.
