Remove extra whitespace in Gmail’s Dense Preview theme
If you have already activated the Preview or Dense Preview versions in Gmail, you must have noticed that there are some extra whitespaces as compared to the earlier themes. Well, many of you may like it but having extra whitespaces along the top and side may not appeal some of you. If you want to have a more compact look with lesser whitespace for Gmail’s Dense Preview theme, you can have it using Stylish or Greasemonkey.
