Make it so you can see exactly who the people watching your trades are.

I can't help but get annoyed when I have four people watching my trades, and only ever get one offer from one person. Like where are the others? Are they planning on offering? I think it would be helpful if I could know who they were and be able to message them. Not to badger the hell out of them, but to communicate and let them know "hey I'm lowering my buyout price" or "I'm going to cancel the trade" or whatever.
