Joost de Valk , a web search engine optimizer from Nijmegen, The Netherlands has created a fascinating new script for every web geek to enjoy. This script could be used to add some data to the Google Webmaster Central Link tool page.

Using de Valk's code, Google Webmaster Central Link tool page will show a website report that covers PageRank score, anchor texts of a link, no-follow links, live links, and image links.

De Valk's website says:

Google Webmaster Tools External links ++Google Webmaster Tools shows the incoming links for your website, but you might want to know the PR of the pages linking to you and the anchor text used on the link. This Greasemonkey script does just that, by determining PR for the link through an XML HTTP request and adding it in front of the link.

If the link is found, and it's normal, the PageRank and anchor text is displayed in black, with the anchor text within quotes.
If the link has rel="nofollow" on it, the info is made orange and striked through.
If the link is not found the info is made red, and the text "Link not found" is added.
If the link is an image link, the text "img, alt:" with the alt text is added. Since v1.1
If a single frame is encountered, the script opens it and tries that for the link, matching Google's behavior. Since 1.1
URL's without www are now properly recognized as well. Since v1.1
