I’m getting a lot of ‘Are you still using Fireworks?’ questions recently, and my answer is ‘Not for almost 2 years now…’. I’ve been using Illustrator CS5 solidly ever since, but part of the transition is going from Fireworks Pages/States to Illustrators multiple artboards. Artboards are more flexible, and allow you to have see everything at once, but the built-in options for exporting artboards are limited.
I use this wonderful script, which provides all the settings I could desire, from format to filenaming. Top work!
