You know how nanos, implants, medkits, and few other things are static in the stores how about doing the same for weapons and armor. There is nothing more annoying then finding a nice weapon that you can use but are a few thousand creds short only to come back after getting the money to find the entire inventory changed. Or to walk into a basic shop to buy a weapon for a low level character only to find weapons that a lvl 30 or above could use. The same with weapons. I'm sure we've all gone through this but I'm sure a lot of people don't have the time to wait and go check every 20 or 25 mins( or however long it takes for the inv to change). It can change several times when your in a mission or out in the field.
Why not redo them so you can bring up a selection of weapons by picking between which ql you are looking for. Picking ql 1 - 10 can bring up seven to ten weapons of different type and ql and some on for other ql ranges. Or something similar to that.
