Updates for Town Hall in Microsoft Teams and Teams Live Events

Teams Town Hall is now really good, Having said that, there are 2 features I would like to see implemented, over has been requested a number of times and believe it in the pipeline, and that is

1 - The ability to change the size ration between the live presenters and the presentation.

2 - The ability to hide the name of the presenter on the live side of the Teams Town Hall,  I use my account to run Live events in my studio, my name is displayed on the studio cameras, the font is also too big in relation to the window size. ( maybe the ability to change the font so small its almost invisible  would help.

3 - Make co-organizers have the ability to add presenters and other management functions, ie,, the EA's often create the events but may me unavailable on the day or days before the scheduled event ( annual leave, sick leave, left the company etc - we create events a month in advance)

Is there a keyboard command that can turn the Optimize feature on and off for video/slide optimization.
