Roots => food - you need this to sleep, remember?

Trading issue => equipped items have their value in gold => this indicates, you wear it. Other stuff is valued in white. I actually like it this way. If my char leads, I see what she wears and if I need the trader to repair my stuff, I can simply switch to the appropriate icon.

If my DK is not leader - I can't see his equipped stuff. So I have to exit the trade window, take him and then I see if his stuff needs repair.

So, only the leading char has equipped stuff in the trade window.
