[Feature Request] Heatmap

[ddeimeke]

Hi!

It would be of some value to get a heatmap for walks.

The color (from green to red) should be evaluated by the count of positions in a certain (configurable) radius.

Example: If you walk a dog (or any other pet), it would be great to see and to understand where the dog sniffs and stays the most.

Cheers
