this is a good step in the right direction for getting a quick glance. also, it would be nice if they added attachment support (if just images) to issue comments, too.

on a related note, my team is working on http://inboxissues.com/ - a browser extension that bridges customer support emails with issues in github. it helps you easily triage issues without leaving your inbox. and once a bug fix or feature gets committed, you can effortlessly notify customers who were waiting on that feature.
