It's worked well, so I'd recommend giving it a shot.
I've been using the system in my BIND campaign. You can see an example rundown around the last index in this book.
I stuck in a few areas as well, so if the players discover 'the Green Tower' in a forest encounter, then that's where it goes forever after, but it doesn't really matter where it lives before that point.
I can't see it. I stuck it in the markdown bars

but it doesn't show when hovering the mouse. I can see it using elinks text-browser, so I guess it's in there somewhere?
