Remap cmd-s (or ctrl-s on windows) to work as a save feature. Particularly on the custom css editor available to ambassadors, but really anywhere in the site where it might make sense. I don’t think I’ve ever wanted the browser default of “save this website” as a file, and as devs we instinctively press cmd-s so frequently; anytime we make a change. Would be a nice touch that I’ve seen on some other web apps.
