I really like it. Though there are some things that could make it a little more user friendly.
I'm working on a server locally, from a client. To copy the styles back to the server, I have to navigate down to the program directory and then copy the files over. Granted, I only have to do it once, but having local paths like multihack would really be great.
The "web safe" color pallette is a bit restrictive, although I CAN just copy and paste hex codes in. But perhaps an expanded color palette?
Just my thoughts.

I'm no expert, but I really like it and have already tossed together a couple more style templates using it.

Great job!
