@andheum: It would be helpful if the Metahopper Group Toggle would change color from on to off.
Oh, it really does 
Thanks once again for all the tools!
Well, here’s the thing that confuses me: when I create a group with Group Toggle by default it is on. Yet the component I want to Hide / Show might be turned off at the moment. After a toggle it works as expected.
The toggle has no awareness of the state of the other objects in the group. You could easily add it to a group where some components were on, and others off. It simply triggers a dumb “command” when you click it.
of course, that makes sense…
