That's a pretty good list, so it seems we've got enough for a review. New Gradient Tool with transparency in gradients.Blob Tool for painting outlined strokes.So I guess the big question now is 'what else does Illustrator CS4 have?' Here's a short list of the major new improvements: Illustrator CS4 breaks the single document mold pretty well too, letting you add up to 100 artboards of varying sizes.

I wouldn't want to have the job of coming up with new features for Adobe Illustrator, because it certainly wouldn't be easy to dream up something new for version 14 of the industry-standard vector drawing program.
