I've tried to use the new Managed Metadata navigation on our new SP2013 site, and it works great for global navigation. However, I have spent hours trying to figure out how to get the quicklaunch navigation working in a contextual way similar to how structural quick launch navigation works. I cannot find hardly any documentation on getting this to work in a contextual way. Is this even possible? If so what steps are required to achieve something analogous to what we had before with structural nav?
One additional detail on this that is important is if you use simple links. I found that it doesn't work unless you use full qualified Url's
path. Simple relative links or links with the
~sitecollection token do not seem to work (even though it says they are supported). The url asset picker dialog (browse) doesn't give you these url's and good luck training an end user to fix the url.
Term driven navigation doesn't seem to have this limitation, but has a different limitation. When using term driven navigation, the sub-sites url segments must be completely different from the friendly term url segment or you will get 404's from the top down.
