Beta Features/Nearby Pages

Goals
Wiki* projects have a huge amount of geographical data. The (opt in) Nearby Pages allows you to surface related pages to what you are reading based on this information.

Key Changes
TLDR: Adds a button to the top right corner of pages that contain geographical information. When clicked you will be able to see what other pages are nearby.

Implementation
This beta feature is currently part of the MobileFrontend extension and is also being trialled in the mobile beta. There are various design challenges to still overcome as well as various bugs and there are many ways this feature could be improved (including much design love). It is hoped that with a bit more work like Special:Nearby this can be a useful and enjoyable part of the reading experience.

Feedback
Is this feature useful? Should we work more on it and use it as the basis to build it into a replacement for tools like Geohack? What's missing?
