Thank you for your feedback. The feature team is planning to add a co-organizer role for Teams meetings. We will share an update as soon as one is available.
We are excited to announce we will soon be releasing the ability to disable all attendee videos, and the ability to disable a single attendee video.
Please see https://www.microsoft.com/microsoft-365/roadmap?searchterms=70620 and https://www.microsoft.com/microsoft-365/roadmap?searchterms=70621 for further details.
The option to “discard” suggested contacts in your chat list is rolling out to users. We will be making further changes to make suggested contacts more relevant for new users in the future as well, so marking as partially completed. Thanks for your patience with this one.
~Alex & the Teams team
