Make it so users can see a 'change-log' upon logging into the developers website.

Allows users to see exactly what changes have occurred between two "versions" (or more) of a particular file and allow these changes to be viewed anywhere in the world by adding online access to the change-logs. Even if it is purely the users comments that they can view, it'd be a start. Sometimes it's important to see exactly what modifications were made in order to decide which file you may want/need to revert back to.
