I think there should be a better market system now that we can search for items. Retainers stand around, look stupid, and nobody browses them anymore. The whole retainer system should be replaced with a "banking" type system. You should be able to go to a main area in the market wards to store all your items (similar to the guild counter, where you can talk to one NPC to store items, one to sell, etc.). Also selling items should go to a main location, and they can be distributed from there to the specific market ward that handles those items. I never understood why I have to go to the jeweler's ward for a sheep leather.

This system would cut a lot of traffic down in the market wards and allow people to get their items sold more efficiently.
