Shade relief by time of day based on sun position
I'd like to see a dynamic shading feature that could show where the shade will be based on the suns position. While looking at a Topo, you add Shade Relief, and then can move the sun based on time. This would show you where the shadows will be for specific topographical features.
I like seeing this to help determine the best sleeping spots to either capture the early morning rays, or avoid them. Also, helps determine potential snow field areas.

I just came looking for this same thing and a little surprised that it doesn't exist by now. As an architect, I have used a feature like this in my CAD software, for at least a decade admittedly for relatively small models not the whole planet. It seems the 3D topography of the US if not the planet exists and adding the simulated sun light would be pretty simple. I am launching on an 18 day river trip in the Grand Canyon on Sept 3, where the high temperatures this week, on the river, at Phantom Ranch are forecast to be 112° every day. Finding campsites with afternoon / evening shade will make a huge difference for our trip. Climate change will only exacerbate this situation in the future and for more places than the Grand Canyon.
