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)
Thank you for your feedback! We are excited to let you know that we are working on this and we’ll check back when we have more information to share with you.
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.
