Quote - I argued that "Library", though not what people are used to, is more accurate. The GUI does not show you your entire Runtime. It only shows you your Library within that Runtime. It doesn't show you textures, geometries, python files, etc.

True, but on the other hand you need a name for the poser-specific, structured and self-contained entity we know as "runtime".
Something like "Poser library" or some such comes to mind. Just to make it clear it isn't just a random folder with a couple files in it; It has to have a specific structure.

Anyway, no biggie. Given we're in Poserland, I immediately assumed "library" must be another word to say "Poser runtime".
