hey, i would code Nathans way too.
a further possibility to go with some advanced custom prefs for specific scene files would be a "txt" file, named exactly as the nk.scene file (actualizing with every saving, or deleting) containing custom function prefs, hooked up by your routine. this helps you, to don't memorize all function parameters, maybe in a nice input mask in the text file, e.g. path="" subfolder="" writenodes="" as nathan said, use the callbacks, e.g. OnSceneLoad
