Just proves once more my inexperience and what an awesome program it is. Good job.
But what I really need to know is how to add a new "top-level" (don't know how to call it) entry;

Is this also possible in S3 or should I use hex editor like XVI32? Or can I just add new controller to existing entry and assign arrays to that?
Ubi made new "top-level" entries for each part, like 1 screw or 1 mast at a time. Thought I needed to stick to that layout, would be lot easier if I don't.
