On the Browse Project screen, there are a number of useful pieces of summary information. But this can only be viewed for one project at a time.
It would be very nice to allow viewing the "Project Statistics" and "Open Issues" for multiple projects. Either by Filter, or by Project Category, or All projects would be great. I don't mind if it's a Report or a screen accessed from the main Browse Project screen.
Obviously, some of the information wouldn't be relevant (like Components and Versions).
