As it is the lists can get pretty long and it can be tedious to get to the item you want. Just wait until modders add 5 new armors, 3 new ammo types for the small-launcher, 14 new HWPs, the ability to build any UFO and fly it out of your hangar, infinity-trillion new grenades including grenades that turn sectiods into chickens and proxies that blow female soldiers clothes off...
The lists are only going to get longer. My idea is to categorize the lists by item types and than by related items, probably using collapsible lists kinda like in windows explorer.
