An application to ‘browse’ the information in the displayed part of the map. Similar to common Wikis and also the main page of http://www.openstreetmap.org the website shows a narrow menu on the left side, most of the page is used for the display of the map. In contrast to most Wikis the menu is not static, but rather the content of the map can be browsed in categories. For the map a special style has been developed (sorry guys, I neither like the default Mapnik nor Osmarender styles), and special overlays are displayed to support the current browsed categories. When you click on an object (either from the list or directly on the map) informations on this object are displayed.
Thanks for your pull request, it's already online!
There's no 'zh-hans' locale in momentjs. I changed this to 'zh-cn', if this is okay for you.
You know that you can add further translations on https://weblate.openstreetbrowser.org/projects/openstreetbrowser/ and this specialized module for date formatting: https://github.com/plepe/openstreetmap-date-format .
