I don't recall when this first showed up but I noticed it first in Revit 2012. Here's what it looks like with a right-click in Revit 2013.
My first reaction was cool! Then I wondered, "When or why would I use it?". Pondered it for a bit and decided that it might be cool if I have a sheet full of details that needed some cleanup. Create a view template and then apply it right quick. Then again I could just select multiple views in the project browser and apply them. With Revit 2013 my view templates will adjust all those details as soon as I change the template, or at least they can if I set it up that way. I suppose this feature might be handy if I forgot to do it and they were all on sheets at this point.
A subtle refinement to process that probably just goes unnoticed? I wonder how many of my readers use it, know about it, care?
