I can't find the original post, but this is essentially a bump of an old thread asking Richard to add a link on the Breakthrough game pages to http://www.trmph.com/breakthrough/board#8, similar to what appears on Havannah games.
I wrote a short Greasemonkey script which injects a link to the editor on LG breakthrough pages, so that should be excatly what you are looking for. I am happy to post it if anyone is interested.
