NavigateTo's Semantic Search helps in getting me from one place to the other quickly (and a better version here: http://visualstudiogallery.msdn.microsoft.com/5437f2e7-adef-44e2-b841-78be850e763e)
We are happy to let you know that we have addressed this suggestion by revamping the entire navigateTo experience and it’s available in VS 15 Preview 5. You can download the bits from here https://www.visualstudio.com/visual-studio-pre-release-downloads/.
I develop dynamics CRM which is nearly all JS and HTML resources these days. these additions would be great because these files tend to be structured for performance rather then readability and none of the other VS navigation features work with them.. where as you rarely (if ever) have multiple objects in the same file in compiled languages so can normally navigate to your destination reasonably quickly without helpers if needed.
