Actually, I hadn't had a lot of chance to play with it yet. I was doing so today. One thing I discovered is that, seemingly, if you load an icon pack and use an icon from it as a folder icon, you don't need to leave the icon pack installed. I guess it copies the icon into its local storage. Which is nice.

I'm also playing with AutoAppOrganizer and App Categories. They're kind of neat in that they try to categorize your applications on their own, the former doing a much better job.
