As I look for ways to optimize my WordPress installs, I've noticed that many plugins include their js/swf/css calls in every post/page regardless of whether the plugin is called on that post/page or not.
I complained about it and you can see that others are feeling the same frustration:
It would be great to have an elegant way of limiting this kind of behavior, like this:
1) In the Plugins page, every active plugin should be enabled cross-site by default, but there should a settings panel where you could make it disabled cross-site by default, and pick and choose if it should only be enabled on all posts/pages/archive/search (I could this being done with checkboxes).
2) In Page/Post Editor, you can override the global setting to enable/disable any plugin for that page/post only.
Does this exist as a plugin already? If not, any takers?
