Mimics a "Compact" density setting for the preview of the next version of Google Contacts, Contacts Preview.
Update v0.2.1: Updated target URLs such that it should now work when logged in with multiple Google accounts. (2015-09-17)
This extension reduces the size of list items on the Google Contacts Preview page (accessible at https://contacts.google.com/). It mostly affect the height of items, so you will have more contacts displayed in your browser window than you usually have.
Upon installation, if you have tabs of the Google Contacts Preview page open, you may need to refresh each of them for the extension to take effect. If you deactivate or uninstall this extension later on, you also will have to refresh tabs of the Google Contacts page to reset the density to default settings.
This extension might cease to function at any time, as whenever a new version is pushed out by the Google Calendar team the minification of the app rebuilds a entirely new map of classes and element ids, invalidating any previous references used for the page elements and styles.
