Allow to open multiple windows.
Want to use two accounts(one for private, one for work) simultaneously.
Or want to check a message while viewing another message.

We are heavy users with many teams with many channels and a lot of activity. Having to switch between chats and teams is very inefficient

The ability to switch to a different team via drop-down helps, but if you are members of two or more very active Teams, it gets quite cumbersome to constantly switch (particularly when each switch takes ~30 seconds in my case at least). I even tried "Run as a different user" which almost worked, but ran into authentication issues due to our MFA configuration...
