Thanks Fabian. This is indeed easy once you described it :) [I assume by OE you mean the Introspector/Explorer(?), because I did not find a way to do it from Object Editor - I am only able to add scripts from the Object Editor]
>From the bottom panel of the Introspector/Explorer it works to add a member just by doing this.books=[]; as you said, thanks. I tried to add it that way from the introspector/Explorer before, but now I see my focus must have been on another property like "_Position" and the bottom pane of the Inspector operates on the focused field, so the field was not added where I expected it - which again makes sense once I know ... [So I thought the bottom Introspector pane did not work ... I did my homework but slopily] Perhaps one more question - is there a more visual way to add a property .. I am thinking, if there was a way to have a List in the Parts bin, I could drag it on my Morph and it would be added it as a member ... I guess I am looking for a way to compose non-morph objects visually into morphs or non-morphs in a way equivalent to how morphs are composed by grabbing and dropping. But that is only an aside.
