Filter on caches found by friends

[+macfreek]

In the map, I can filter on caches not found by others, and caches found or not found by me. However, I also like to filter on caches found my friends.

 

The use cases is that I have a few friends (at https://www.geocaching.com/my/myfriends.aspx), and sometimes they tell me about recent finds. Since I don't want to look up details during a conversation, I like to look those up later. I can find them on the friend page (although I must say that is pretty hidden, 5 or 6 clicks away), however, I also like to get an idea how far away these are before I decide to chase them. So ideally, I like a filter that shows me cache I haven't found, but which were recently found by my Geocaching friends.
