Hello Phoenixrising ,
1.You can have a perm pop-up change the data contained depending on the panorama viewed by adding a text area in the pop-up. But the text only support still pictures and words, do not support embedded links and pictures .In other words, if you put a link in to the text area, you can only see it but can't active it.
2.Thumbnail can open its scene, but can't open the popup.
