It would great if on the drupal.org user profile pages the user's sandbox and full projects could be separated. This would allow a viewer to quickly see how many sandbox and how many full projects a user is committing to.
The problem
When I am evaluating a project I almost always look at the maintainers profile page to see what other projects the user has committed to. If I don't know any of the projects by name I look at some of those projects to evaluate them for usage statistics, bugs, etc. This process takes much longer if I have to click through to a bunch of sandbox projects to find full projects(if any) that I can evaluate.
Evaluating the maintainers involvement in other quality projects is much more important in evaluating new projects that themselves don't have high usage or issue queue histories yet.
Proposed solution
Somehow separate commits to sandbox projects in a separate section below full projects. I love sandboxes and I am thankful for all the work that was done to implement them on drupal.org. But sandbox projects are not full projects and don't have the same criteria to evaluate them.
Clearing delineating full project commits will improve the ability to evaluate projects. This is especially true to new members of drupal.org who don't immediately recognize the names of users and projects.

My preference would be to either group them according to these criteria or add an indicator beside each item.
