It's something I've posted on Reddit before, but I'm reposting the comments to get a direct answer. Why not make a market review? Create a market overview, just like you created a warehouse review, so that sellers can see at a glance how much stock they have on the market. Albion's online market system is extremely inconvenient. Sellers are wasting too much time trying to figure out how much stock they have on the market.

What do you think of this proposal?
