Multiple windows for MS Teams?

Why doesn't MS Teams support multiple windows?  It stands to reason that if you are on multiple chats, editing a file, and trying to join a meeting, you don't want to leave each ongoing action behind to go to the next, and shuffle around try to find where you left off in each section later.  Even separate windows for chat would be a huge help, or allowing a meeting to launch a new window outside of Teams and leave whatever you were working on in the original window.  Most people use multiple windows and multiple monitors to multi-task, and I'm surprised that the only way Teams seems to allow this is to run some of your windows out of a browser?  Is there help coming to make this a more productive tool?  This feels like a downgrade from Skye for Business...
