I agree with your last point about the knowing which file created the interest. And since the new version to be released is offering (better) support for direct connection (to my knowledge), these ideas could be very useful. (Although, if this sounds dumb, why not respond with "which file fare u talking about?") But the SEND FILE button/option to the Chat Window sounds good. The only thing I'd worry about is a group of people who constantly share between themselves & give preference of their connections to them. But I guess those things would be considered in such programming design. What were the other ideas you had?
