The size of hotspots looks fine on a desktop screen, but they are tiny and almost invisible on my smartphone. How do I make them responsive so that they are visible on small screens without making them huge on a desktop? Or is it possible to make PtP use hotspots on a big screen and automatically switch to another way of navigating on a small screen, e.g. a (hideable) bar with thumbnail images of the panoramas?
Responsive platform-conditional UI plugins are in the development pipeline.
