It would be great to be able to protect or unprotect individual cards/widgets on Dashboards, which overrides the general protection setting.
This would be useful for Dashbaords that allow for some interaction, but where you don't want filters changed.
E.g., You have 4 Task list cards you don't want to be edited, but you have a Note card that you want to be able to freely write in without having to unprotect the whole view.
