title: Sublime Text 2 : colour of edited file tab?
body: <p>I see that the Sublime Text theme (.config/sublime-text-2/Packages/Theme - Default/Default.sublime-theme) can be edited to make the open tab more obvious.</p>
  
  <p>For that I use</p>
  
  <pre><code>{
      "class": "tab_control", "attributes": ["selected", "file_medium_dark"],
      "tint_modifier": [0, 255, 0, 32]
      /* ... */
  },
  </code></pre>
  
  <p>which makes the tab greener.</p>
  
  <p>Is there a similar method for colouring the tab of an edited (unsaved) file/buffer?</p>
  
  <p>Thanks.</p>
