We Really really need this.... deals that change don't have a frame of reference any more..... It makes it really hard to know what you were working on with someone.....

I think you're asking for a trade changelog / audit trail, which some other people have been asking for as well. I could use one too!

Or maybe a setting to email a copy of each deal you propose or are proposed when you receive the email about it? that would be really handy....
