Rotterdam Routes

I like the tour idea, and the audio content is interesting. It's nice to be able to download routes beforehand. The navigation cues seem accurate. But several improvements are needed: 1) Add 'allow location while using app' privacy option 2) Audio content should play automatically when you near a highlight 3) Audio content and navigation cues should continue playing when screen is turned off 4) Audio content should restart after a navigation cue is played. Currently audio stops if a cue is spoken and can't be restarted without backing out to the route map and replaying the entire audio. 'Navigate to route start' would be a nice feature. Overall I've enjoyed using the app, but it's a pain to remember to disallow location usage when not using the app so my phone battery isn't drained.
