It is ultra annoying. Thanks to new Steam chat they can somehow send you messages. Not only they open a new window, which means closing a full-screen running TF2 or anything else, they are completely useless! If I'm an average IQ human being, I know that I have ordered, let's say, a few weapons I lack and I have to: 1. Accept the trade; 2. Confirm it through my Steam app. There is no need for them to inform that they have sent me an offer, because I expect it AND the Seam itself does it! Besides, I'm sure just removing this feature the bots will act more quickly - not that I complain about their speed, but sometimes they seem to overheat. Just a honest question: why this was added in the first place? What's its purpose!?
