New progress: The German GUI and all the events and functions for the category 'General' finished successfully.
Now I start to design and code the English one.
The current basic functions: Better and very improved functions.
E.g. MeizuCenter detects whether it's already running and if you want it kills the already running instance.
For people who know German:
Then MC detects if there's no device plugged.
In addition MC has a splash screen. It shows while MC loads the main functions and the GUI.
