Feature request for 4.3.0 (BB2 on every page)

In my hobbit configuration I've many pages and subpages and one feature
that I would really like is the possibility to have a bb2 page for every
page I'm in so that for example if I'm in the "Unix Server" page that
contains "DB Servers" and "Application Servers" I can check directly all
the "non green status" from that point in the page hierarchy.
