title: Where are the default packages in Sublime Text 3 on Ubuntu?
body: <p>I'm migrating from Sublime Text 2 to 3. In Sublime Text 2, I changed a lot of the default settings of the editor -- such as the tab bar height, sidebar color, etc. -- by modifying the <code>Default.sublime-theme</code> file in <code>sublime-text-2/Packages/Theme - Default</code>. I was also able to modify the colors of the default color schemes in a similar fashion. I've been trying to figure out how to do this for Sublime Text 3, but can't seem to find these files. <code>~/.config/sublime-text-3</code> only seems to contain overrides for user settings, not the default settings.</p>
  
  <p><a href="http://www.sublimetext.com/forum/viewtopic.php?f=2&amp;t=10933" rel="noreferrer">This link</a> on the Sublime Text forums seems to give the location for Windows and Mac, but not for Ubuntu. I've searched a bit to no avail. Does anyone have suggestions?</p>
  
  <p>Thank you!</p>
