I'm currently knee-deep in CSS gradient generation, so this is very welcome. It would be nice if there was a way to shift all the colors in a gradient simultaneously - for hover effects, you frequently just want a slightly lighter version of the same gradient. In Photoshop you'd do this with an adjustment layer (which still isn't perfect).
