Yeah, the first point is silly. It's trivial to run minified CSS through a prettifier. As for workflow, pretty much all the CSS meta languages have some sort of auto compiling upon modification and you can skip the alt-tab (assuming you've got enough monitor space to see the browser window and your editor - and if you don't, you should fix that) and refresh by using LiveReload. As for tweaking the styles in the browser, never really understood that, but Chrome has (experimental) support for Sass source maps so you can see where the styles came from in the Sass file directly.
