This is wonderful. I have a theme schematic that's doesn't handle plugins too well. This plugin worked on that theme, and of course every other theme.
Sure, it takes a second to get used to. But once you're used to handling the controls, the amazing performance and flexibility it gives you is unparalleled.
I know some people complain about image cropping and all that, but if you really practice with the settings, you'll get the hang of it, and it'll become second nature. It's not a bandwidth hog, and won't affect your YSlow scores or page speed/optimization -- if you were using a clunky plugin before, this will probably improve it.
I'm using this on all my domains and replacing all other slider plugins with this.
