title: How do I enable editing features in Sitecore page editor?
body: <p>I'm using Sitecore 7.2 and trying to allow a user to set things like datasources and some custom parameters on sublayouts in page editor mode. The user is a member of sitecore\Designer and sitecore\Author, but when that user tries to edit the component properties, the fields appear grayed out/disabled.</p>

  <p>I am able to enable these options by setting a user as an admin, but don't want to grant quite that much power to this particular user.</p>
