It would be nice if we could only show this checkbox when prompting for screen
share. Is that possible? Having a checkbox that essentially says "I might not
mean anything" is pretty weird. WDYT?

Or we may move the checkbox to below the window/screen selection, and depending
on 
what the user select, we enable or disable the checkbox.

In that case, disabling checkbox will show a tooltip explaining why the checkbox
is
disabled.

P.S. We are on the other hand developing the tab sharing, for which audio share
is 
possible.
