But again, this comes down to knowing the tools better. I've done probably as much CSS as the developers you mention, so I'm not completely talking out of my ass. I just want to make sure that people realize what their editors are capable of before doing manual workflow optimizations. 1. With all things equal, I'd say that the developer that is able to scan a vertically aligned list of attributes can do it fast. Plus, there's no horizontal scrolling. I'm not saying one-line scanning will be slow, but I'm arguing that with equal practice, vertical attributes will simply match what the eye is able to do more naturally. 2. In Textmate, you can fold all the attributes, and see a essentially a list of your selectors, with comments. 3. See #2. I wonder if the developers you mention ever gave using symbols lists and code folding a shot before manually adjusting their workflow to mimic those features. I really do believe that if they did, they wouldn't be using the one-line approach.
