Nice thing to be added - more "readable" info about each item
GUI would be a nice thing yea

And the main thing - an ability to buy on ever sell your items (controlling user inventory).

Seems hard to be done but worth it, great idea!

E: noticed that it does not actually show items in market real-time. As i updated the market page, there were 2 new items placed, but the CMD screen doesnt see it. It seems to scan the market after login and pause.
Yet it needs to be done - make it refresh its data each # seconds so as someone put an item in the market, it will be displayed on the screen.
