Feature request: freezing (or blanking) the shared screen content

[novoid]

What problem are you trying to solve?

Many times during screen sharing, I need to quickly switch somewhere else, type in a password or do something else which no other participant should see.

Currently, this requires to cancel the whole screen sharing altogether, do whatever I need to do and then - very tediously - re-start the whole screen sharing experience including searching for the proper windows to share and so forth.

This is far from quick and really drops me out of any presentation flow I was having. It also annoys the participants because they often don't know why the screen share suddenly stopped.

In my opinion, this results in many situations where the presenting person decides to do the other thing while the screen sharing is not stopped. With that in mind, this is actually also a security feature which is currently missing in Jitsi.

What solution would you like to see?

Just like most projector remotes do offer, I'd like to have an easy to reach button within Jitsi to freeze (or blank) the screen as it is currently shown. After invoking, the participants continue to see the frozen screen content (or a black/white screen). The presenting person should see an easy to spot indicator that the screen content is frozen (blanked) with an easy to reach button to re-enable screen sharing.

Is there an alternative?

I don't see any other alternative except stopping and re-starting the whole screen share which is tedious to do and requires much more effort.
