I would like to be able to resize the window smaller than it currently goes. I'd like to have it take up half the screen. Given that this is a Microsoft product and windows has the built in snap-right/snap-left feature, I'm quite surprised that this program does not support this. I think many people would want to have chat up, while also using another program. Same for video calls. It makes no sense that the screen can't be made smaller - both chat and video are content that can easily be resized, and are just as usable at a smaller size.
