How long has it been since you used element/matrix? Serious question because the new element call stack is now finally released in element stable, as of a few patches ago. (It still only shows up as the "video rooms" feature that u have to enable in the labs/beta settings)

Its much cleaner than before and properly supports screensharing, adjusting individual user volumes and more. The previous jitsi based voice rooms were somewhat lacking i admit but they have been functional for years.

That was the last thing that kind of kept me from fully endorsing matrix but now it does all that really important stuff. The new mobile ElementX client also supports the new call system but its overall lacking compared to the normal mobile client which does not support it.

But for desktop use i dont have any complains anymore about matrix really.
