Well,

All custom templates will have a check box next to them, so if you want to delete them, you just check them.

Perhaps, from only single styles because when you add a new hack, you only get templates in the default style don't you?

But whatever's easier - maybe having a link or checkbox for deleting from all styles will be very useful too.

Then when your templates have been checked, click submit and they delete from the style and the database
