A nice improvement to Allura project/code hosting would be a personal dashboard when you are logged in. It would provide quick access to the projects you are a part of, tickets you have created, tickets assigned to you, your pull requests, activity stream of people you follow, etc.
Since there are many possible components to this, a pluggable structure like the user profile page would be good. Some parts of a public profile (like projects list) could be re-used on the personal dashboard too.
https://forge-allura.apache.org/p/allura/tickets/7171/ is a related Allura ticket about seeing your own ticket votes. https://forge-allura.apache.org/p/allura/tickets/5419/ is an additional idea for showing projects that match your skill categories. (And many new tickets for the whole dashboard idea would have to be created to divide it into manageable tasks)
