This is significantly easier to use than BBMASK though. (Perhaps that's why you 
don't like it?)

I think we need to be realistic here as I said in my most recent reply to the 
other thread - people will do this using whatever mechanism is available 
whether we like it or not. And what are they saying by doing so? They're 
effectively telling us that they can't consume the recipes in the way we are 
currently collecting them together. We know what the proper fix for the problem 
is (increased splitting of large layers such as meta-oe), it may not be easy 
but other than workarounds like this I don't see an alternative.

Cheers,
Paul
