The software that is being written in order to check and reformat CSS files is progressing nicely. I'm to the point that most of the CSS spec has been implemented, warning codes are generated, and this is getting significantly closer to being usable. We are writing unit tests to make sure that the software works as expected, and I'm very thankful for these tests. They have exposed a couple bugs that my test CSS file didn't show, and the code is much better for it.
If this tool looks like something that would help you out or fill a need of yours but you need some modifications to get exactly what you want, please don't hesitate to contact me. I want to make a general-purpose tool that would really help a lot of web developers and UI designers. To that end, if I had more people who write CSS for a living and they were to email me with the features they would want, then I would have a much better picture of what's needed and a more complete understanding of how this tool could assist others.
Stay tuned for more updates!
