Allow multiple windows or tabs
Allow for multiple windows or tabs in the desktop app to browse teams, chats, the calendar, files etc. Currently, having to change the window every time instead of having the ability to keep open what you're working at. It is very frustrating to have to navigate from the main page every time instead of just being able to jump from window to window or tab to tab.

Here is a workaround to open multiple Teams instances. Open Teams in your browser and you can use several browsers to get to different Teams modules. Address: teams.microsoft.com
BTW, There are several entities of this same idea. Someone may want to combine them into one.
