This is a very quick Illustrator CS3 tip that will hopefully save you some time in the long run. I'm sure a lot of you, if not all of you, know how to load a Brush Library. There are 3 ways, actually, but my favorite and quickest way is the Brush Library icon.
In the screenshot above, you can see that it takes 3 menu levels to get to the brush libraries that are grouped into folders. If you use the “Brush Library Icon” in the bottom left corner of the (any) brushes palette, you eliminate the first menu and jump strait to the libraries. Again, just a small tip, but I know from experience that it's easy to get used to doing things the same way every time. If you can find a way to break a habit, maybe you can save a few of those precious seconds throughout your day 🙂
