Add: SyntaxHighlighter (wordpress.com)
The SyntaxHighlighter by Alex Gorbatchev is widely used on blogs with code samples. It is served as static content by Wordpress.com, but often takes ages to load. Inclusion in Decentraleyes would be great for page loading performance, if this is possible at all.
Not sure whether wp.com always uses the same URL for the js library, but here's the one I found so far: https://s1.wp.com/_static/??-eJzTLy/QTc7PK0nNK9EvyClNz8wr1i+uzCtJrMjITM/IAeKS1CJMEWP94uSizIISoOIM5/yiVL2sYh19yo1yKiotzgguzAEaZ59ra2hiZGRsYmRobJIFAI/MP6c=
There are some more libraries on wp.com that would also be of high interest, but I'll start with this one.
Cheers, Uwe
