Simply put, would be nice to one click to a user's other non-closed threads in the marketplace.
Makes shopping/selling easier to manage I'd say.

On that note, a simple button next to the pm/profile button to search a user's posts is welcome as well; see geekhack.
^A.t.m. you have to login to be able to search quickly, going from a post to someone's profile to his/her posts; or directly search, username. On GH it's: see a post, click username, click show posts; without login.

Not sure how easy it is to implement the first thing, but I'm planning some improvements to marketplace navigation, so I'll keep it in mind.

GH must be broken, that kind of profile/search used to be closed to members. Also it doesn't show posts since 26 March?

Thing is, you can't see the profile itself- and that's prob a good thing.
Just searching for posts made by a user is always possible, be it through google or the regular search (enter 'author: user') only that's more unnecesary work.
