<p>Just following up after the Gin BOF at DrupalCon Europe.</p>
<p>The UI of both Claro and Gin has a lot of visual space and in many ways this is a welcome improvement, especially for content editors. However there are times when a site builder or editor may prefer a more condensed layout.</p>
<p>Please provide role based or user preference tool for controlling the theme density. Similar to how gmail does it, screenshot below.</p>
