Urgh... yes, that's right. Would there be a clearance property that someone might be able to use if they wanted to manually remove these? Someone might have 2 of their own filters added, so it would be good to access the ones that have been tweened and remove them at will. I guess someone could just perform an array diff or something though to get around it, so it's likely a code solution is better for this (rapidly becoming more) particular scenario.
