Nice article and good tips. I just don't know if this guy is using the same Zoom that we are, but my team finds it a UX disaster zone.
We do a daily standup where 4 - 6 people are calling in. Zoom only supports showing 4 chat windows at a time. So if you're on a call with 6 people you literally don't know that two of them are there until they start talking.
Try out "gallery view" (next to the fullscreen button) — it's much better than the default "speaker view."
