title: More than one folder / project in one Sublime Text 3 window
body: <p>I can have only one project / path opened in in the same time, in one Sublime Text 3 window.</p>
  
  <p>Each time I quickly switch project (<code>Ctrl+Alt+P</code>), new project replaces current one. Each time I open new folder (<code>File &gt; Open Folder...</code>) or project (<code>Project &gt; Open Project...</code>), it is opened in a new Sublime Text window.</p>
  
  <p>Can I have more than one project opened in one Sublime Text 3 window? If yes -- how to achieve this?</p>
