I have seen a bunch of post on this topic, but none seem to have answered my particular problem, so here goes.
When I put contributed libraries in the folder C:\Users\Matei\Documents\Processing it does not show up under File>Sketchbook
though it does find them under Sketch>Import Library
But if I change the folder in preferences to C:\Users\Matei\processing-1.5.1\New folder, for example, it does see the libraries under File>Sketchbook but not under Sketch >Import Library
Is this how it is supposed to work? Am I doing something wrong? Is it Windows fault? Which option is better?
