Snippets are a pretty cool feature of VS 2005.... aka Intellitasks to some... and Gus has created a tool to make them... (well, he did back in March.... :))

Snippy - A C# code snippet editor
I made it my weekend project to hack up an editor for code snippet files.  If you don't know what code snippets are, you should check out these two entries by Shaykat and Anson.  Shaykat provides a good overview of them in general and Anson touches on them a bit more and shows an example of what the XML for these looks like.
