title: Multiple editor windows with multiple tabs
body: <p>Very often I work with multiple projects in MATLAB and have a group of files for each project that I access at one time. Having all files of all projects open causes a lot of clutter in the workspace. One can do this for one single set of files by <a href="http://blogs.mathworks.com/community/2010/06/07/editor-tab-switching/" rel="nofollow">docking</a> which is well known.
  Is there a way to tab projects, or have multiple MATLAB editors (for each project) open with multiple tabs in each (with the projects files). The question can be found <a href="https://groups.google.com/forum/#!topic/comp.soft-sys.matlab/h5yLeFu-2k8" rel="nofollow">here</a> too. In the same vein, are there other code editors which can be used to perform the same?</p>
  
  <pre><code>Project1
      file 1.m
      file 2.m
      file 3.m
      file 4.m
  
  Project2
      file 1.m
      file 2.m
      file 3.m
      file 4.m
  </code></pre>
