I do software development with a team as a part of my graduate research. We are involved in a number of projects hosted in various places: some on public GitHub projects, some on a private Redmine instance, etc. Some logical projects are split into multiple project repositories, often with some public parts and some private parts. We're using the issue tracker for each project for its respective hosting location, which is good except that we now have a lot of places to check and I'm worried we're approaching "tool overload" - too many places to report a bug, too many places to check for bug reports.
So, the question is: Is there an aggregator tool/web app that we could configure to show us at least a combined bug list from multiple different bug trackers? It would be nice if it could also show a combined "activity feed" (as both GitHub and Redmine offer), and even better if we could add 'one-off' external bugs to track (something in an upstream bugzilla, for instance) but now I'm really getting into dreamland.
I don't know of any ready-to-run aggregator tools, but you should be able to use Ticketmaster to build your own as it provides a consistent interface into various providers including github and redmine.
