Dodaj kilka diód. Chodzi o informacje czy wciśnieęto capslock, ins, czy przyszła poczta itp.
Myślę, że warto też zrobić miejsce by można było tam wstawić raspbery pi pico 2040 lub jakieś inne procesory. Jak by było to autonomiczne bez zasilania po kablu to wiele osób by chciało miec komputer na swoim *(tu wpisz procesor) ulubionym procesorze
