Well why not make drop-down menu of all the items? Like Click and the pick Barrels, Sniper guns and only what you pick shows up.
It be great if we can track all stats too. Like a drop-down and pick Aim, So all Aim items only shows up.
Allso now whit Augments kits. Have a check box that say. "Have materials". Click it and all stuff you can make shows up.
basically have drop down lists to show Stats, per Gear slot, Lvl and Gear Type.
And now that I think of it we do NEED a way to see what schematics we have learned when we browse the GTN.
