@rglides Thanks for these, all really useful! The snippet and zoom examples help a ton.

@dannytaurus What if that container has many items just for it, this would mean if I wanted to see the "Audio Loop Player" in this case, I have no way to minimise just container 1, and keep that one open. Or we could just make the "Container" just that and do exactly what you have in the loop you made. Just containers do that function, others still work the other way around. - Seems odd to have a processor called 'Container' but it's more than that.

I agree with the 'disappearing' arrow, so you could add a 'placeholder' such as (No processors) or even a cta for "+ Add processor", sorry if I'm getting processors and modules the whole way round.

@dannytaurus Yes the ongoing issue with things appearing and disappearing. I believe removing it with no children is a more accurate quick fix, as having a button that does nothing and looks like something else is much worse.

Realistically there is probably a even better solution but that will need more time and deep diving.

@David-Healey

There is a slight conundrum with this. In edit mode, that arrow does close and open possible items of that container to add. If none are set then outside of edit mode this arrow then does nothing.

This means the arrow is a signifier in UX terms, but in some cases, looses it's purpose and further to your question now looks like another feature.

So solution? If the processor (Container1 in this case) has no children, do not show the arrow. The Arrow itself implies there is something inside - if there is nothing inside then the arrow should be removed.

TL;DR - Remove button when container is empty
