I would like to have a carousel view. Especially with many participants, I can imagine that the view of the other participants in the carousel has a relaxing effect.
Please provide more details about how you see this being implemented and its benefits. There are already a number of options fo managing your webcam view:
Everyone– Display all attendees in themeeting(those not sharing their camera will have initials).
Who's talking– Display only the current speaker.
Active cameras– Display only those who are actively sharing a webcam.
Hide everyone– Display no webcam. This will help increase bandwidth if you are having internet issues.
