It would be handy if the passage guide and other resources such as commentarys had the ability to "follow" whatever happens to be active at the moment just as is possible in cited by and power lookup. You could have a passage guide and commentary open along with bibles from link set A (primary focus passage) and another set of bibles from link set B (secondary passages based on primary) and the commentary and PG would follow whatever set happens to be active at the moment (just like power lookup or cited by or explorer).
