Bad news gang, the market window default settings aren't anywhere within the market window that I can see. (Bear in mind i've been staring at xml coding for the past 20 hours refining our new Auto Updater version of the ThorUI before it's release. So I may have overlooked something...)
Sony's UI staff has the market window in a state of limbo at the moment so it's hard to tell which way they may go. (Old controls are still there with new controls hidden when viewed with the UIBuilder)
When looking at the raw xml; It's coded in a way that it receives the info from Sony "There isn't much I can change". (The default settings for the window as most of you know, load your current characters level as the "Max Level Value" along with your class. This as you know infringes on our nice little "Search for Item" button from the store window working to it's full potential.)
Good news is:
Since the window is in a state of limbo and obviously having issues (vendor text not showing on most items) I really can't see Sony leaving it this way for long. "Although as I type that I can't help wonder when they are going to ever start sending the groupmember health and power percentages promised back at LU12

"
Longwinded post summed up:
Search "kind of works" for now...
We'll have to wait on Sony to make a change.
