7. Why is there no button for hotspots on/off in some panos? If so, then there are no hotspots at that site for that time of year.
8. Why do some panos pan in on a different view when I want to crossfade to another time of year?
This has to do with the technique of how the panos were recorded in the field. There are two types of panoramic images, and it happens only when crossfading from the one type to the other.
