TidBITS: What You Get Is What You CSS, With Style Master 4.0 - sounds very interesting, a program with which you can edit CSS files and display them directly in connection with various websites. I must take a look at it, because manually tweaking CSS files and experimenting with them can sometimes be quite annoying. Being able to prepare something offline would be quite nice. Update: sorry, but after a first test, the thing has been kicked off the plate. Good idea, slow and unintuitive implementation.
