Copy protection is not a big worry for me.
There will always be people who want something for nothing, especially VJ's who are starting out.
It would not be a massive issue if they were shared with a couple of friends or colleagues.
If the price is low enough, say $5 or less then you'd have to be a (insert derogatory term) not to pay for it.

It makes working with 3D objects almost totally unviable, we cannot achieve anything other than very basic styles.
In my opinion this really should be a priority for you to implement and should not be a feature request.

The problem is because the iteration which you want to replace is still there, cut list is not functioning.
The fading iteration is just being placed on top of the existing one.
I think you need to build the iterations with a different method or maybe someone else can figure it out.
