Now about FurnitureLibraryEditor-1.31.jar it simply crashes when I try to edit something in my exported own furniture library (I couldn't share because I don't know who created models I had to convert, import, texturize, etc. You know some very same models are published by various people and it's impossible to know real creator.)
It seems to me Furniture (and Texture) Library Editor would be better when integrated inside SH3D as plugin.
