Unfortunately, I don't have access to VS2013 anymore so I can't really contribute any improvements unless I can find a maintainer.

SassyStudio 2013

SassyStudio 2013 extends the SCSS functionality found in Visual Studio 2013. Looking for Visual Studio 2012 support? Checkout out the original SassyStudio

So far what's supported:

• Compilation (libsass/compass/sass compilers are all supported)

Upcoming:

• Smarter compilation (understand imports)
• Sass 3.3 support
• Intellisense Enhancements (custom functions, etc)
• Feature parity overall with original SassyStudio
