For Teams Breakout Rooms, give the participant the ability to select their own breakout room by title.
Sometimes it is best if participants can choose their breakout room themselves, based on their own interests/needs, rather than having the organizer assign the participant to a specific room. Give participants that power to choose a breakout room!
This would be extremely useful when organising events that have various rooms covering a range of topics. Organising large department events and allowing staff to join the room of their interest means that collaboration is more dynamic and discussions are had with people with the most interest and contribution. We recently looked at Toucan a video conferencing tool that offers the breakout room facility as it allows participants to freely join the room they wish to and move around the different rooms during the event. Teams breakout rooms would definitely be more powerful when this feature is implemented.
