Hi,
Not sure if this is the right place for posting feature request but anyways here we go:
I have been thinking about this for a while and I think it would be awesome to have a new placeholder available for the Wayfinder template say "LevelDeepness". It would store how many levels deep the current item is situated in the manager document tree. If a placeholder like that would be available to me for things like say ul and li it would ease styling navigation listitems a lot.
There is the &levelClass parameter which will add the class level1, level2, etc to the output
