• Add the site name, not only the ID, like for groups resources for example
• Add the package name, not only the ID
• Add the Self Service notification check box
• Add the Self Service compliance category checkbox
• Add the user interaction restart message
• Add the ability to upload a Self Service icon <- maybe a must have ;-)
• Add support for scope limitations and exclusions (lke in configuration profile resource) <- this one is also a must have
