I've never used simplicity. When I first started out, I used another theme, modifying it to suit my needs. But onceI started building my own, I've never gone back.

It has some features, but what makes litestep litestep is the ability to exercise your own creativity. I like the minimalist approach, myself. My current theme has a desktop sized at 0, 0 and -0, -0. The whole screen. I have a little bar with a clock, winamp controls, an lsxcommand window, a button I can hit for my popup, a button I can hit for my current tasks, and a systray that grows and shrinks. The whole thing fits within the title bar of an active window when it is maximized.

So, I suppose I don't use simplicity because it is not simple enough!
