The Raspberry Pi has a set of standard components. Plasma in its current state is not possible to run on such a small screen elegantly, neither is the hardware made for the DE. Goal with this is to look at what a hypothetical desktop environment based off of Plasma/Kirigami/Qt would look like.
This is the View of the desktop with both Global Menu (housing task manager, systray and system buttons) and Content Menu (housing Application Menu) open. The idea being that since we know the exact screen size of the Pi we can make something that works as good as possible on its screen size (800x480px and 154x86 mm)
