Nice link, lots to play with there. The script doesn't seem, however, to display the internal links within a page. I am making a glossary (of horology), which is getting seriously complex, and has lots of internal <a name="blah"> links, from highlighted words to the "mother" definition. Snooper shows all of these as well as the off-page links, and is thus very useful.
Highest praise for Opera. Author/User mode switch (Shift>G) is so handy for zapping those 10pt. lime green-on-black-backgrounds. White pages hurt my eyes after a while, so I use #fff0c8, which is gentler. One of my favourite features is the "Windows Native" appearance option (Shift>F12). Nice to have a browser that doesn't look like a teenager's bedroom...
