We have a few hundred users and dozens of projects in our Stash instance, and we expect it to become even bigger.
To encourage collaboration and innovation all developers can see all projects, so it's quite a long list of projects.
It would be nice to be able to group projects so that it's easier to find a certain project, and it would also be easier on the eye.
The group names should be completely customizable of course.
Example use cases: Grouping projects by area/subject, companies, departments, operating systems, platforms or programming languages.
