not privacy conscious. but in slack, during the huddle call, when someone shares their screen, slack app gives an option to separate the huddle and the screenshare in 2 different windows. it is very helpful since the screenshare window is a floating window so i can also multi task. Whereas on browser, the whole huddle is a single window and i feel restricted. I used to stick with slack on browser slack but often times its very buggy and i had to force switch to slack app.
