Quick question. What do you use when none of flags apply? I am trying to make an array plugin; pf_singleglobal wouldn't apply to it, since it'd have to be multi-instanced. None of position/size ACE flags apply, either, since array is not a layout object.
So I set "flags": null, however that appears to cause a glitch; even though it is a non-layout object, when you add the object, it goes into layout placement mode. Click and it throws error.
