double click vs single click is interesting, seems nobody knows how to handle an object needing to be interacted with more than a single way.

Maybe the right idea is to just pick one arbitrarily and stick to it consistently.

I’m only mildly joking, UX guidelines are basically just this. There is no way to make people implicitly know how to do things (skeuomorphism was a solid attempt).

In society it’s only things like hammers that have a universal/innate understood use.
