some useful add-ins for visual studio

Today I installed the following add-ins for my visual studio 2008:

1. NShader: NShader is an extension to Visual Studio 2008/2010 that provides syntax highlighting for various shader languages including HLSL - GLSL - CG..

comment: I think this one is more concise than some other similar add-ins

3. RockScroll:

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|Add-in Manager just by un-checking the checkbox.

4. Visual Assist X:

this is a famous add-in for visual studio, it’s useful though the intelligence reminder sometimes can be annoying.
