Hi Jarek, I have seen some designers make sure that they have the nested input element in their designs, even if it is not connected to anything, why is that? I mean their nested designs don't have any actual input but for some unknow reason (to me) they put that element there. In general do nested designs have to include nested input or nested output elements, even if they are not connected? I never add a Nested input element or nested output element when I don't need them, but I just wondered maybe they do it bc of some logics which I am not aware of.

I don't remember now why this decision was made, it was a long time ago. I agree it doesn't seem necessary in general, it may be something to help with initialization. And maybe also an ability to detect a nested design (which is otherwise indistinguishable from a standalone design).
