For all these fancy new options (99% which we will never use), MS have ignored or never considered the simple biggest feature that is sadly missing i.e. ability to share screens two ways simultaneously.
When working with a colleague remotely, we often need to share a screen for other to view.
Then many times the remote colleague has to take over screen sharing to show something relevant to discussion.
After that, we then return to sharing first local screen.
So we end up flip flopping a lot between local and remote screens.
Most of us have two screens - it would be the most magnificent development if we could share a screen from user A to user B and using our second screen we could share from user B to user A. This would seriously enhance productivity as we could look at both screens simultaneously rather than "my turn, your turn, my turn, your turn ad infinitum"
