Being able to open teams in multiple windows.
If I'm working on a file in teams, and then want to send a message, I don't want to have to get out of my file, go to chat and then go back to my file. I should be able to have multiple windows open (and spread them across my screen), dedicating one to chat's and the other to working on my relevant files.
They are apparently working on it. Your comment and votes may be more visible here: https://microsoftteams.uservoice.com/forums/555103-public/suggestions/16926739-multi-window-for-chats-and-more
YES! This is definitely needed. It's a massive pain to be able to have only one thing open at a time.
