I found a great plugin to get syntax highlighting in Visual Studio :
https://nodejstools.codeplex.com/releases/view/104141

The issue is this plugin made for node.js so it works only with .jade files.

As .dt are really close it works fine, but when using layouts files aren't found cause file extension (.dt) is hard coded when vibe.d parse the extends keyword.

Is there a way to customize the extension vibe will look for?

I think it would be nice to use :
extends layout.dt
instead of
extends layout

so
extends layout.jade
will work to.
