@Cole I can think of a couple.
1) Locking the stage for all participants is a really cool feature, especially for Meetings that are not setup as Events but follow a kind of formal presentation format, but there are some nuances. I find that a lot of users who are not Webex-savvy don't change their layout and just leave it in default grid. So as Host you can turn on the "show active speaker on stage" and lock the stage and it's like a nice webinar experience outside of a webinar, especially with shared content. works better when everyone else is muted of course.
2) I think immersive share is cool and not enough people use it. That is a snackable option to present.
