That's neat. It seems like it isn't available in OsmAnd though, sadly.
I enable this when I want to zoom to a random place in the world without first downloading a 600MB map file, want satellite imagery, or indeed want to view different styles. I wish there was better integration, like being able to also search worldwide with online services when this view is enabled (but it's also not like I got time to implement that myself so I can understand nobody else has gotten around to yet, either).
