A new feature to generate script documentation(HTML file like JsDocs). Also we should be able to modify the template (e.g : JSDoc takes only /** and */).We should be able to specify our own template...
I use Jsdoc and a custom template to produce documentation of our framework in html website (see attached printscreen).
By tweaking the code of jsdoc you can tell him to accept your kind of comments (which is really not a standard one).
But i agree that a feature to generate automatically documentation would be nice (even if building doc with jsdoc it is very easy and fast) so +1
