I fail to see what does not work. Renaming Spec-Core to ValueHolders works. Even if ValueHolders isn't already there, it is created. The only thing I encountered, the ValueHolder entry wont' show up in the rename dialog, if - the Package doesn't exist (of course, thats ok) - the Package is empty ( but it still works). Or should we prevent to rename a category *XYZ if package XYZ doesn't exists? Nicolai
