about-dialogs: Show information from AppData, link to Software
About dialogs exist to show information about an app. Nowadays Software is a much better way to do this, since it includes reviews, add-ons, licence information, and so on. It would therefore be good to link to Software when possible, in order to provide more information.
Along similar lines, AppData provides a range of information about apps that it would be good to show in about dialogs.
These mockups show how this could be done.
