Multiple Master Profiles
Under Set Master Profile, the ability to store multiple profiles would be a significant improvement. Though the storage requirements must be minimal, if that is an issue, make the additional “secondary” profiles exportable as a file which must be hosted and URL provided. Save the URLs in the Master profile in order to display/select them. These four should be pretty basic to add and would greatly add to the ability to make each installation more useful to specific site and company needs.
