Page contents to <title> tag

[sbk]

so many sites have bad titles, this document.title method could be a general filter, that can be customized from an include-exclude or other list file.
_________
my purpose is only to bookmark and only a few sites worth the trouble, so i have a few site-specific filters. the filter creates link to the same page at location on the page where the usable info appears. simplified fake example, before:
<h1>text that should be good title, bookmark</h1>
after:
<h4><a href="\u">text that should be good title, bookmark_website.com</a></h4>
