People don't manage to reply to comments

Quoting Ossi from a mail:

this is apparently something a lot of people get wrong:
don't reply to review comments by mail. it hurts collaboration (as the
mails are not publically archived). and i get "spammed" if you don't
take the sanity bot out of the cc list.
the correct way is hitting the "review" button and adding followup
comments. if you want to reply to particular inline comments, open the
diff view for the patchset the comments pertain to and use the reply
buttons there (note that you still need to use the "review" button (of
the right patchset!) to actually submit the comments).

So this is a feature request to add a reply button next to the comments or make it somehow clear that the right thing to do is to hit the review button. This will save us some headache when opengov goes live.
