Compact Density for Google Apps
Surrounding the launch of Google+ in 2011, Google's “Project Kennedy” redesign started updating its apps to provide a more consistent experience, but also to take up more space, which can make them feel cramped on smaller screens. These extensions reduce unnecessary padding to give you more room for content. In some cases, where the Kennedy redesigns removed helpful colors (e.g., blue links), these extensions also restore those.
These extensions are now obsolete, as Material Design has since replaced Project Kennedy, and many of these apps have been updated with their own density options and responsiveness to smaller screens since then.
