Before i found litestep i tried aston, it was really hard for me to configure because it assumed i had certain programs and tried to put buttons on my desktop for photoshop (which i dont have) it also put a bunch of links on my desktop to websites like tucows etc. I didnt want that garbage so i deleted those "groups". Then i couldnt get another "Group" to come up so i killed aston. Litestep, with its ots standard means all the themes follow a certain set of rules so that its easy to configure new themes. Litestep is much more configurable and easy imo.
