Maybe it has been overlooked, but I would appreciate it if the new stuff -whats new since your last visit at the marketplace- appeared in a different color.
Also, not all items in one big marketplace, but different smaller places, one for horses, one for weapons, like its in native.
These two changes would make it a lot easier to find the stuff you really want.
Me for example prefer buying a light armor at the normal shop, because in the time I need to go through all these items I can grind the gold on the servers..........
