Hello All, I'm new to the group and Jessica's site, so I'm not sure where to post this but did you know that there's a free abr brush viewer for the Mac (and PC see end of post)? You can see a preview of all your Photoshop brushes from within the file windows or by using "cover flow" and you don't even need to open Photoshop to see the previews. It's a file that can be downloaded from this site:
brushviewer.sourceforge.net/
Once you download it be sure to read the "readme" file and it explains how to install it. Basically you just drag the file into in the QuickLook folder (located in the system library folder). Then anytime you look at an .abr file you will see a preview just like you would for a .jpg or any other file. I love this utility and think you all should go download it a check it out. It's also available for the PC (I use both platforms, but really love the Mac for creativity!)
For PC users - I haven't tried this on my PC so it may work differently

I've been using this for a while and love it. If there's something else out there, I'd love to hear about it. I hope this helps someone!
Let's Keep in Touch!
