Simultaneous screen sharing

Hello!

When collaborating at work or study using Zoom, I find that the option for two participants to "exchange" screens - show me yours and I'll show you mine - is very helpful.  However the option is now only supported using dual monitors.  I'd like to propose that finding a technical solution for doing so with a single screen (for instance, you'd see only part of each screen) would still be very helpful.  We can't always have two monitors ready!   I hope that this proposal gets support from the community and interest from the developers.
