In which file do i code this functionality thank you

Does anyone know how can change the default functionality of clicking on a subject in IdeaSpaceVR with mouse hover?
Instead of clicking on a hotspot for example, I need to execute the same thing with just placing the mouse on the hotspot.

thanks a lot

Every time I upload an photo-sphere picture, the app resizes it automatically and the results I see its very shrinked and blurred.
How can I fix this?
Is there any option to manually set it to my own needs?

thanks in advance
