Granted, usually it's pretty obvious. Klingons go with the Klingons. Humans go with the Federation. Amazing! There are times it's not always so obvious though.
It would speed up searching on the exchange if they were divided by faction, especially for KDF since often there's a couple pages of FED options before you even see one you can grab.
Seems that since DOFFs already have some sort of system that prevents them from working in the "wrong" faction that it wouldn't take *that* much work to add this.
I think this is a minimum. I would love to sort by traits as well but by faction is a minimum. Personally I think the exchange should be geographically/faction separated and that would help, but thats a discussion for another day
