Indentation marker/vertical lines for Python in pydev

Is there a setting in Pydev source editor (Aptana studio for Eclipse) where I can see what indentation level a particular line in a Python file has? Something like a vertical line or a marker on the top/bottom window edges (as seen in image processing tools).

When having source code with a couple of indentation levels is can be quite hard to see what level it has:

def foo():
  while True:
    #stuff
    #stuff
    if "foo" == "bar":
      #stuff
      #stuff
      while False:
        #stuff
        #stuff
        #stuff
        #stuff
        if "baz" == "baz":
          #stuff
          #stuff
        else:
          #stuff
          #stuff
        #stuff
    #stuff ------> would be nice to have some visible cue that this is on level with the 'if'

Doesn’t look like it is available out of the box, however it is possible to add with plugins, for example:

or you can configure to show whitespaces, however, it doesn’t give you vertical indent guide, unless you willing to count dots: Preferences -> General -> Text Editors -> Show whitespace characters
