Sharing screen in the previous version were better because window were borderless / transparent opacity 0%.
Please, add the possibility to hide profile picture in the call, they take a lot of screen space.
Remove window mode version (I have to click on float mode each time the other person share screen).
I want my mouse to disappear when I don't move for a while.
I have the same requirement. In float mode auto hide all skype stuffs(display pics, buttons etc). and show when i move the mouse
