Hi Martin,

> Hierarchy would suit me better

I think that will come from a "Group" mechanism which will be a separate thing from an "instancing" mechanism.

Components/instancing will be focused on making copies of a base object in such a way that the copies are lighter weight and can have their base object changed and have all the instances then update to reflect the change.

So far at least I've been thinking that a Group mechanism with hierarchy would be separate from that. Although maybe there is some possibility to combine things together but not if those combined mechanisms become too complex an unwieldy with too many options compared to how separate mechanisms would function.
