Saw this thought in the forums. When one deletes Mcafee for any reason one loses all settings that one setup in firewall and scheduled scan etc. It would be nice to have a export settings and import settings option. Of Course this would only apply to same versions not different upgrades as they can have new settings.
Another idea along this line would be to warn you if settings are changed say your kids change permissions to blocked programs. This could be a file that logs changes.
These and stopping settings being greyed out when program expired might be a good idea for future products.
