There are a lot of “projects” that actually span multiple FS projects. For example, if someone asks how they can help with DJDNS development, I have to point them to a bunch of separate links for the component technologies (EJTP, DEJE, DJDNS, pymads, and occasionally persei), or my own profile page.
That's not really ideal.
What would be ideal, would be a way to create “groups” of projects, where you can see issues for all projects in the group. And when a new project shows up, is sponsored, etc., that information should be subscribable via email or RSS or both.
Because the use case is so important to me, I'm willing to pay a whole bunch for this feature - around 3 BTC personally. Others will probably find it promising too.
