Known Issues

• [v1.x] Initial loading might be slow as the maps need to be cached in one step. A progress indicator is missing as well, as asynchronous loading cannot be tracked at the moment.
• Firefox: MapOn/Off Control not visible
• [Feb 2017] The location of the Sternschanze in the map of 1694 is not quite correct. Re-rectification of the map seem necessary.
