Controlling settings, permissions, and membership within Teams and channels
Ditto here... a feature really needed to effectively groom an evolving Team Community.
While I'm dreaming...
It would also be nice if it were possible to copy as set of Team Chat messages into a channel as a conversation. I can't count the number of times a thread is started in a chat conversation that really should have initiated in a Team Channel. Just like moving a conversation posted in the wrong channel to a new channel... it would be useful for Team Chats as well.
