Where does plasma 5 store its configuration?

[Valerio Passini <valerio.passini@unicam.it>]

Hello. Today I've faced a problem with a widget and I needed to reset my plasmashell configuration, but I've been puzzled by the fact that configuration files seem have been moved from .kde to .config. in my home directory. I would like to know if all the kde plasma 5 configuration is now moved to .config and I can safely remove .kde because it's unnecessary. Thanks
