Factorissimo but instead of a factory warehouse it's a copy-paste circuit warehouse. A composite combinator combined with combinations of combinators from a combinator combinator
i think you mean "player.opened=nil".
The menu may flash for a single frame, but there isn't really an issue here because you're teleported to the combinator surface, which puts you out of range of the combinator (and on a different surface) so the gui closes immediately.
I'll add this to the next update, but this doesn't really do anything.
