categories in ppm and menu
Having installed defaults-chooser I have stumbled upon not yet optimal behavior, see image.
Success message of ppm does not use translation of category which is in Puppy-Setup.directory and is used for menu.
I have translated Setup into Konfiguration
Maybe a TEXTDOMAIN just for categories could solve this.
