Is there a reason this has to be picky about what kind of navigation is being
scheduled? I'm not thrilled with adding more locationChangePending() callers.

Good question. For the specific user of the API, it doesn't seem very
interesting. Should I just change it to isNavigationScheduled?

[Nate Chapin, 2015/08/21 23:00:29]

I think that's preferable, yeah.
