Thanks for the swift response!
Yes, if I could be informed of every route change - the I can probably build a time calculation around this event, and work it into the data logging easily enough.
However, how to intercept/listen in for a route change? (Reasonably generically). I.e do I have to modify all views - activate/deactivate - or can I set up a single event listener?
Thanks!
