Suggestion: Show the age of listings within my own merchant tabs
I'm the kind of seller that continuously reprices my items downwards in order to make quick sales. It would help me with merchant tab maintenance if I could see which of my current listings haven't sold in a bit, so I could adjust the price accordingly.
This info is already available on the trade site and in game trade listings, so this information is being stored somewhere. I know how to access this info, but going to another tab (or worse, to an internet browser) to look up my own items, and then back to the game to locate them within my own tabs, feels a bit silly.
Just an additional line in the tooltips would be great, but GGG loves to work themselves to death so I'm sure they could come up with something better.
Even if you (royal you) wouldn't ever use this feature, I imagine still wanting it to exist simply because people like me would use it, which would probably translate to more downwards price pressure in general.
