I would like to put forward a feature request regarding the Image Hotspot content type.
First, make it possible to upload 360/panaramic images that can be panned around by a user. This would allow the creation of location based teaching resources that allow online users to interact with a place they can't physically visit. For example, I could go to a forest and take a 360 image and point out all of the important features to students. (A long shot, but this could also eventually be integrated with VR tech?)
