These are some very useful new features that I'm excited to try out for my next flight. The wind particle animation is just great.
I agree with Dave about the slider, though. And regarding the wind en route—that's a feature I've been wanting for a long time. However, is there any way to incorporate actual numbers with the coloring? A static legend would be okay, but might take up too much space. Maybe we can tap a region of that graphic and get a tooltip? On a related note, I've always thought it would be nice to have a draggable tooltip with exact elevation on the "Terrain en route" trace. Perhaps we could combine the two vertically—imagine a slider across the bottom of the Navigation Log screen that populates the values of winds at each altitude, plus the exact elevation at the corresponding point along the flight path. Maybe these are simply static images that can't be queried as such—I haven't taken a look at the code to understand the implementation.
Anyway, these are already awesome features to have access to. Thank you for implementing!
