I think this will be a concern regardless of how it’s implemented. In the participant pane, if there are a lot of people, the indicator will be hard to see also;
While you may be right for lots of attendees, the situation would be improved for (the majority?)
of meetings with less than fifteen participants or so.
you would need to scroll through. The focus indicator is actually very prominent and perhaps easier to notice even.
For me, the focus indicator stops being of any use with nine or more participants. For two to nine, I can hardly notice it due to reasons given.
Even worse: when screensharing is active, there is no way for me to tell who is talking at all because there is no UI element except when I switch back to tile mode where I can’t see the shared content any more.
So my proposal would provide functionality Jitsi does not provide at the moment. Compared to other meeting solutions, this is quite frankly a bit of an embarrassment to us when we ask our business customers to join our Jitsi meeting instance. But this is just my personal experience.
The background color can always be changed for better contrast. Again, this is already possible and depends on the person’s preference.
I don’t know how to modify the background color. This is not obvious to the average user.
Furthermore, this would not solve the current issue of no contrast difference between active and inactive microphones or cameras.
I really can not follow your rationale here, I’m sorry.
