Hi Klaus,
my problem is, that i can´t really seperate the skin layer from other code.
Delete everything after line 290 „skin layout“ to the end of the file (deleting all the actions as well): Hotspots not working anymore
Deleting everything from line 290 to 365 (= until gyro plugins“): The skin on the bottom is gone (that is what i wanted). But if i click on a hotspot and change scene, thumbnails appear without any layout on the top of the browser window. Very strange. /the menue on the left in the screenshot is the menue i build, but on the top you see the appearing thumbnails)
