Yes.
Both groups are right in their own environment, as usual. (There's a blue cloud of obscenities over our college that was recently reported on the Toronto weather station ;–)
It's a great feature in production mode but the clutter is highly intrusive when you're working in concept and visualization mode.
(Which makes it a perfect candidate for an “on-off” switch.)
With InDesign serving very different needs for different pros, these kinds of production guides should always follow the interface maxim “The user is the chooser.” (Which Adobe does follow in many cases.) Then users are free to pick the best work mode for themselves.
As information designers who also do all of our own production, we absolutely need to turn these kinds of production aids on and off on the fly.
I originally switched to InDesign from XPress because it was a better visualization tool, and it has become a great production tool along the way too. But this one will have me gritting my teeth in pain until it's changed.
Now I'm off to the Feature Request form at Adobe. ;–)
Thanks for the input, as always!
Cheers
Tom
