What would you change in Heroes of Might and Magic IV?

I would like to have the option to sell items and artifacts at the market in the town. Sometimes you need money, and there's a lot of unnecessary junk accumulating.

Yeah, I remember writing about that... When I first appeared on the forum. And yet, it exists in Heroes of Might and Magic III :( But they missed this feature in Heroes of Might and Magic IV. You can collect so many artifacts, but you only use the very best ones. I usually give the rest to other, weaker heroes. But I would like to have the option to sell them...
