title: Android Studio gutter preview for drawable
body: <p>I didn't even know about this gutter color/drawable preview feature until recently saw it on another computer "turned on" by default...</p>
  
  <p>Anyway, back to my workstation, I try to enable the feature but have no luck.</p>
  
  <p>Basically, for example, when I open colors.xml, my screen looks like this:

  <p>In my settings, I think I have the required options checked to enable gutter preview:

  <p>So where is my color/drawable preview in gutter? They are not shown both in xml and Java files.</p>
  
  <p>Thanks/BR/Richard</p>
