That would indeed be nice! I will hold off on the proposed LFUN since
your proposal is much more elegant and useful. There's no hurry.

I think that your proposal would actually work for Pavel's intended
workflow as well. Pavel, do I understand correctly that

  inset-forall Branch:*:active inset-toggle toggle

would do what you want?
