Custom comment formatting (like VS10x Comments Extender for VS2010)

One of my favorite extensions for Visual Studio is called VS10x Comments Extender. It allows you to setup custom formatting for comments that are typed in a certain manner. 

From the VS10x page:

How does it work? Well, when you start a comment with // (C#, C++, F#) or ' (VB), you can add some extra characters (minimum one, maximum three) in order to define how this comment will look like. VS10x Comments Extender will interpret these prefixes and format the comment accordingly.

It REALLY helps to see this in person... check the link below. I think this would be a GREAT addition to an already great text editor.

Look for all the examples here:
