OS image effects?
 

I've been looking at the app LineForm, and OmniGraffle definitely leaves it in the dust. The one thing that LineForm really stands out with, though, is the ability to apply core image effects to objects. Things like dyamic blurring and halftoning effects can make a world of difference when whipping up images in OG.

Any change this might make it into a future version? Pretty please with sugar on top? *grin*
