Organize Teams in Teams
Would be great to organize the Teams that I belong to by being able to use folders to put them into. I have multiple teams that are related to the same topic that are named all over the place because they have different owners. Even though I can put them next to each other it still gets messy.

It should be possible to arrange the various views (teams, chats, file repositories, etc.) in whatever relationships you like.
