AlpineQuest & OfflineMaps

In the lower left, we see there is now a Google Street View coverage layer, as seen in this screenshot from Google Maps.

It would be great if this layer was available within the Offline Maps app.

You might say, that I am confused: these are not Street View images, but just blue lines showing where the street view cars went. Yep, that's correct! By the way, they're perhaps are a few more layers in my image that haven't been added to the Offline Maps app yet too.

Yes, I know there's a button to suggest them. But I don't have their urls handy.

Yes there are a lot of Google layers and not all of them are available in the app, especially not the ones that must always be up to date (like traffic) or will require internet anyway (like street view).
The Google Maps is better for this data.
