Would it be possible to add a checkbox for "always use this topic for navigation"? Some types of information lend themselves to nesting, and tend to be revisited frequently enough that using the upper-level topic for navigation is very likely. Some examples would include: dungeon/building map, spell lists, treasure tables, wandering monster lists, etc.
I don't know that this has much value above "low-hanging fruit", but I thought I'd toss it out for consideration.
