Almost five years ago, I had the honor of writing a post on Smashing Magazine about my Photoshop panel GuideGuide. Since then it has seen wild success as the most installed third-party Photoshop extension, an achievement I’m quite proud. In that time, I’ve added some powerful features and, most recently, expanded it to Illustrator. This post will give you a taste of how GuideGuide can change the way you use guides in Photoshop and Illustrator.
