I'm think about my JS projects in terms of modules (basically, files) that import other modules and export data or functions.

Since ES2015 syntax makes it pretty obvious which values are exported, I'd love to have an option for documentation.js to always render documentation for those values, even if they don't have a JSDoc comment (!). I know this may not always look great, but it's better than not having a complete list of the API surface.

For items without a doc comment, using humanized exported name (camelCase/snake_case to separate words) as a title should suffice.

(Similarly, I'd like to have an option to hide non-exported items in the documentation. That's not really important to me, though.)
