Plasma should be able to have different themes for same data.For example there should be 10 different Clocks, while all of them are showing one thing: Time. So Plasma Provides Data Engines. Data Engines will provide Data for Plasmoids.
So to have a Clock Plasmoid:
Plasma --> Time Data Engine
KDE TechBase |---> Clock Plasmoid 1
|---> Clock Plasmoid 2
