There are new versions in the first post, and house numbers now appear at zoom=19.
The biggest change is that the themes make use of tags on maps from OpenAndroMaps that indicate access by bike or on foot. Tracks now have access indicated down the centre where this is mapped (blue=bike, orange=foot, green=bike and foot). Hike and bike networks are indicated similarly on roads, as well as by large blobs.
Colours are derived from UK Ordnance Survey, if you wondered.
Getting correct font sizes and zoom levels at which symbols and captions appear is not easy, depending on screen resolution and density of mapping in your chosen area. Voluntary UK dp on Locus makes a valiant attempt to scale appropriately for your display.
PS. Uploaded revised version of Voluntary Atlas due to bug in turning circle code.
PPS Added updated key to this post.
