Thanks for the kind words about StyleURL. I didn't know about the Changes panel until recently, that's going to help a lot of developers. Behind the scenes, StyleURL parses the CSS and uses an AST to do the diff'ing, rather than generating a character-by-character diff like one might see in a pull request on Github. StyleURL creates a more helpful diff because it ignores irrelevant changes (such as whitespace). As a comparison, on Hacker News, I changed the font-size on body from "10pt" to "12pt". Screenshot comparison: Changes panel: https://www.dropbox.com/s/qa57kvsazglx22y/changes.png?dl=0 https://www.dropbox.com/s/qa57kvsazglx22y/changes.png?dl=0 StyleURL: https://www.dropbox.com/s/5g8erdiskdskkhx/styleurl.png?dl=0 https://www.dropbox.com/s/5g8erdiskdskkhx/styleurl.png?dl=0 This is a contrived example, but most of the diff shown in the Changes panel is unintentional whitespace changes, whereas StyleURL's diff only shows valid CSS that changed.
