Of course, gmail could have broken their interface
since then. If they make
it impossible to edit quotes for relevance, then they have
no place in
civilized email, like any other MUA with that property.
Not broken, on web or android (I can't speak for iPhone). On web, click the
a little 3 dot icon and the text opens to edit. For this thread, however,
the most important feature is 'mute'. I'll be using that next. :-)
