Hi

If I pull up aerial photography of an airfield using an Androoid device a layers symbol appears on at the top RHS.  If I click on that and select "view in maps app" then a number of apps that I have on my device pop up such as Alpine Quest, Uber, Zoom etc.

This is very useful as I can then go straight to the OS map for the area using Alpine Quest and find footpaths etc.  I am puzzled though as to the criteria by which the apps that appear are selected, whether they are selected by Syydemon or Google maps/earth and how I might add a further mapping app to the options.

So, is there a list somewhere on my device and can it be edited?

Thanks
