Microsoft has announced a new feature for Teams which launches this month!
The new feature will enable all users to view meetings and calls in separate windows from the main Microsoft Teams client. Additionally, meeting and call controls such as mute, video, chat, leave and others will now be located at the top of the meeting window so that they are always available and never block the underlying content. This new experience will also include recently announced features such as 3x3 video, raise hands, and custom backgrounds.
This will roll-out OFF by default, giving users the ability to turn on the new experience via the user setting: General > Turn on new meetings and calling experiences.
After a couple of months this function will be default with no further action required by the user.
