Currently, when a user logs in, the page that appears is the same as the "public" page: lists the projects of the month etc. However, login implies the user likely wants to do some admin stuff on one of their projects or account. So I'd like to suggest that once you log in to sf.net, I should see the list of my projects in the top section. Actually, the projects of the month shouldn't even be shown, they are irrelevant when login in.
Even better, some summary data about each project would be nice to see in that section, making it a table instead of a list: for each row (project), show latest activity type (such as News, Ticket, Project Admin, etc) and date, number of downloads since last login, date created, repo type (SVN, Git, Merc), # developers, license type, etc. Clicking on any of the table cells would jump to the corresponding page of that project. For example, clicking on the latest activity item would jump to the News page if the activity was a news item.
