When the Google Maps Engine app hit Android in late 2013, it enabled users to view and share custom maps. Now an update has landed that empowers them to create and edit such maps as well. Users can spawn new ones, add layers, and move points around as needed. They can then go back and rename aspects as they wish.
The update has also introduced some UI changes, so while it may look largely the same, it's a little cleaner around the edges.
