Whatever I try, I don't manage to edit the css while live previewing the html page (like they are showing on this screenshot ). Is anybody managed to do that? Every time I make a change in the CSS, the preview pane show me a "preview" of this CSS file, which basically show me the same code, but without colored syntax. This screenshot is really misleading about the capabilities of this software. What's up with the text-wrapping too? No way to uncheck soft wrap, really?
