This is a general point for all 3rd party code and has been on my mind for a while. What I'd really like are developer plugins that are documented not just functionally but architecturally.
Ideally they would be something you could pull off github, read the docs and understand the main architectural concepts involved (say, autocomplete) and then easily extend. This would be of far more value to me than a plug-in that try's to do everything under the sun for a mythical end user.
When I first started using jquery, that's exactly what I thought plugins would do.
To my surprise, a huge slice of plugins are basically non-flexible widgets. This is rather childish and useless. Why would a javascript developer want a fancy styled fragment of a page?
