I was looking at a new (to me) video editor for Linux and noticed the author had put together a rather nice system for tracking (and presumably obliterating) his FIXME's. Here's the link: http://diva.mdk.org.pl/2005/08/03/fix-the-fixme
Or, if you want to skip straight to the result, here's what it produces (try clicking on the FIXME's): http://diva.mdk.org.pl/wp-content/fixmes.html
Just thought you guys may find something like this marginally useful. Hope I helped ;)
