So I have noticed it is very cumbersome to move around in the wiki--for instance, when I am embedded in a page, I would like to move back up one level to get to the original page--to do this I usually have to hit the back button and go through the edit screens until I get up to the level I want, or else I have to go all the way out and drill back down.
It would be much easier (and more elegant) to use a cookie-crumb trail when I could easily navigate back to one of my upper level wiki pages.
