I posted an update to my KeywordClassifier Visual Studio extension today. This update fixes the manifest so that Visual Studio 2012 compatibility is better detected, and also adds JavaScript support for both VS2010 and VS2012. Here's a screenshot of how it looks:

I also updated the version of the extension that is posted on the Visual Studio Gallery.
