From e9953fa5e6985045c599eec6d63572ee7bb458d7 Mon Sep 17 00:00:00 2001 From: Henrik Brautaset Aronsen Date: Tue, 15 Jan 2013 22:45:18 +0100 Subject: Show single dives in map. This adds a "Show in map" entry in the dive list context menu. It will zoom to the dive location if it exists, otherwise the full map will be displayed. I've also switched map tiles from OpenStreetMap to Google Maps just to show off that we can.
