Scott Hanselman has released RockScroll, a Visual Studio addin created by Microsoft employee Rocky Downs that can be really useful when working with large, ugly code files. In his own words:

The basic (as in “only”) idea is that RockScroll extends the scrollbar in Visual Studio to show a syntax highlighted thumbnail view of your source. This is really useful for those excessively long source code files you know you have. It’s just one DLL and you can turn it off from Tools|AddIns just by un-checking the checkbox.

The only problems I have with RockScroll are that it doesn’t support JS files and it doesn’t handle collapsed code too well. Other than that, it provides a set of interesting features: for example, double-clicking any word in your code will highlight the same word everywhere it is found in the same file, both in the small “preview” area and in the code area. The addin works nicely with VS 2008.
