Ability to Switch Shared Screen and Other Improvements
It would be nice if you could switch which monitor / application you are sharing without having to end the screen share and restart. It would also be nice to have the option to share your screen with your own camera showing you in a small window and better yet, make it so these options can be easily turned on / off and set by default (at individual or admin level).
In my opinion, Zoom gets this right - better than just about any other solution out there in terms of the customizations and features available.
Last request - the ability to save / record screen share sessions for later playback or export.
