I've been missing this button. Works well in light mode. Button icon barely visible in dark mode.

Thank you! I have become so used to working around the "Smart Reply" (which can still be useful, just do not call it "Reply All") limitations I had almost forgotten how "Reply All" used to, and should work. So far, this add-on appears to work as desired.
