JSDuck offers user feedback in the generated documentation. Sencha uses this on their code doumentation. It is described in a blog post.
I would like to use that commenting feature for our development team too.
Who knows how to do that?
JSDuck now has the commenting feature available as a different project... https://github.com/senchalabs/jsduck-comments
JSduck itself can be used if you want to do something along those lines... https://github.com/senchalabs/jsduck
