HTML and CSS: Better "quick documentation" and "external documentation"?!

Please, file JIRA request

Currently both "quick" (ctrl-q) and "external" (shift-f1) documentation
for html tags and attributes and for css are linked to some page from W3C.

Much better documentation is available at sitepoint's web site:
http://reference.sitepoint.com/html
and
http://reference.sitepoint.com/css
(See screenshots to compare docs for "background-color".)

Would it be possible to either
- generally use the sitepoint docs instead?
- make options for W3C and sitepoint?
- make a general option to configure the documentation provider?
For example using templates to specify the URL given the
tag and attribute names, resp. css-property. To make this really useful
one would have to be able to specify a javascript snippet that would run
prior to rendering the page (to remove unwanted content).


I skimmed the Open (and close) API and it seems somewhat complicated to
write
a plugin for this, so I am asking about the chances to include this in
IDEA.

Thoughts?
