Photoshop Express has it... my WP7 has it... the old Windows Vista previewer had it. Even when I do auto levels/curves/tone/contrast etc etc, and then after all that tweak the color balance/saturation/shadows/you-name-it, and I still can't get it to look as good as those 1-click auto correct features, well, it gets frustrating. It may be that I'm not an expert enough (though I'm a 20-yr graphic designer). But why should I HAVE to do all that, when a perfectly good 1-click feature like the one in PS Express could work just as well and save gobs of time? Is there already a feature like this and I just don't know about it?
