… yes please! tell me if you need help. we (OSEG) could probably provide a test room for you guys on our BBB instance, so you can easily test it for a few meetings and then look for your own, if it fits.
Zoom on Linux, in my experience, is really terrible to use, in many ways. It tries to be smart: goes to full-screen every now and then, without being prompted to, minimizes without being asked to, moves to a different desktop while doing so, and disregards everything about UI design that we are used to from software.
