I would ddo the pee pee dance if this were fully supported feature in a future release of vb.... god i hate updating my templates when upgrading.
I had this installed for the last 2-3 upgrades, however i found it rather complicated to utilize and it just seems that it is easier to revert the templates and do the template edits manually (for me).
(Antivirus wishes that Andreas brings this to dev team in next dev meeting and it becomes implemented in future versions...)
