title: VS 2010's Productivity Power Tools's Tab Well on the Right Side
body: <p>I once managed to position the tab well vertically on the right side of VS's GUI by tweaking the registry. <br>But I can't find out anymore how I did it.
  Please refresh my memory.</p>
  
  <p>EDIT : <em>Before having this recent interface (see answer), These were "hidden" option that needed to be tweaked like described <a href="http://blogs.msdn.com/b/visualstudio/archive/2010/06/21/document-well-2010-plus-hidden-options.aspx#gradientsforcustom" rel="nofollow">here</a></em></p>
