I'm having fun with code in my new Directions app. I've added an Auto Advance feature that will move from waypoint to waypoint automatically and then wrap around from point B to point A. You can just click the button and watch the route unfold. Flip it into Satellite view, set a cool Pitch and Bearing and you can fly across the country visually for as long as you like.
I considered an adjustable timer so the user could determine how long the app pauses at each waypoint for reading, but I scraped that and wrote a timer that counts the words in the text and apples a constant to it. The number I came up with that matches a normal reading speed was 420 milliseconds per word. So, a waypoint with a longer description will allow you more time to read it. Did I mention I was having fun?
