The main tabs(right_tab) highlight to indicate which page you're currently on. It would be great if the subnav links had the same feature.
maintab hilite is based on body_class, which (of course) will not work for subnav. See also http://code.pinaxproject.com/tasks/task/485/
Maybe basing nav hilites on body_class is wrong in general?
no reason why body can't have two body classes (or more generally, one per nav level) but there are also other approaches like having a base template for each subnav with an "active" class on the li itself.
2 body classes? Ok, that works. See:
http://code.pinaxproject.com/paste/sL7w/
But: limitation with 2 body classes: it works if nav levels are strictly hierarchical: that is, a body class will appear on only one nav level.
E.g. it works for project/tasks because tasks does not have a main tab. For company/projects, where both company and projects have a main tab, it causes both main tabs to be hilit.
See http://github.com/bhaugen/pinax-groups-experiments for one way to do this.
