While the warning message in the Restore Default Dashboard window on the RestoreDefaultDashboard!default.jspa page tells the user it will delete any pages that have been created - this is not how the function should seem to work when selecting the "Restore Defaults" link from the bottom of the Configure Dashboard page.
Since a given dashboad is selected (the name is highlighted) when the user selects this - it would be more intuitive if the restore only restored the defaults for the selected page.
Example: I have 2 custom dashboards that were created after the "default" dashboard had been modified. I would now like to return the "default" back to it's original layout but don't want to lose the 2 custom dashboards. Unfortunately this is exactly what happens if the Restore Defaults feature is used.
