I don't post here often, but here's my little throw-in here:

When you right-click > Display Set, the Gear Set Viewer comes up.

I think it would be easier if this window allowed you to change gear in here, and then have an update button on the bottom. That way, for example, if you get rid of a main weapon that you had and can't equip the gear set any more, you could just go in and replace the weapon and then update it. Not a major change, but just another little thing that could be added.
