Two ideas for Trade Center Adjustments.

1) Blacklist/Exclude Keywords:
Essentially something like the Keyword field, but one that allows players to either Blacklist certain words for their account or just add an extra field that will allow a player to see trades that don't have a certain keyword in the title.
This one isn't really for me, but I have seen some people complain about being annoyed at the "Trading up" challenges some people do. I don't have a problem with it at all, but I figured this could probably benefit both the people doing it and the people that prefer to avoid seeing it.

2) "Frozen Lions":
Pretty much self-explanatory. Essentially the opposite of the "Exclude Frozen" button, where you can choose to only see trades that include frozen lions

Additional suggestion from #107570:
Adding an option to only view trades that don't have a set Buyout price.
