For layouts that keep elements on one page at a time, it's great.
the feature gap is when working on a booklet with page bleed. It really needs a way to handle page spreads... laying out a magazine with elements that run across the gutter is difficult without it...
For example, if you are using page bleed, and want a title to span across two pages so that when the booklet is open, the title rolls across the entire space, it's nearly impossible to line this all up without a lot of registration marks, work, and hassle.
If there's a way to do it, I can't figure it out. :-(
otherwise, very nice.
