Oh, and I nearly forgot: I'd've liked to create the kind of hint you get with official objects when you pass the mouse over its in- and outputs (you know, those flashy explanations in dark gray bubbles). I only found the hints and annotations in the inspector window, but they're less cool. As you can see in the patch above, I tried to imitate those hints with bubble comments, but they're static. So, is it possible to create those hints also for your personal objects?

Ok, I answer myself at least the last question (maybe it's useful for somebody else): it's possible to have comments on in- and outlets of abstractions. You have to open the actual abstraction, click on an in- or outlet and then open the inspector. There you can add a comment. That's nice!

ok, thanks! But this answer seems as if other content containing objects, maybe [coll], [histo], or [funbuff] would eventually share their contents if used inside an abstraction. Is there something I (and surely other users) should know?

Thanks!

I see ! Thank you for this info.
