We have a request to number the participants in the participant list. This numbering would be dynamic so as new connections join, they are shown with a number next to their name. If someone drops from the conference, the list is renumbered so there are no gaps. We have this need for board meetings where issues are voted on. When you have a large group, the numbers would help determine if there are enough voters.
I know you can see the number of participants by going to "Meeting > information" and scrolling to the bottom of the list, but that is static and require quite a bit of "rinse and repeat" to keep the current count accurate. Even having a dynamic total participant tally in the participant title bar would be helpful.
