Meet the new pop out apps feature for Microsoft Teams
Multitasking while working in Teams was one of the main limitations of the platform, having a chat with someone, while looking for content in an application was a bit annoying and forced you to switch context multiple times.
Microsoft was aware of this limitation and with the last updates has been introducing pop-out windows that allow you to detach calls, meetings, and chats.
With the latest update of the Microsoft Teams client, you will be able to pop out personal apps and tabs so you can continue to have chats and collaborate while working in the app.
