@JoeCFD Yes, I do. Also, I just realized that my approach to changing the status bar colour does not take into account the existence of the navigation bar (I'm not using it, but some users might). Therefore, the whole approach is not suitable.

Currently the only rule I am aware of is that all the files you put in the .qrc must in the same folder or in a subfolder of where the .qrc file lives.

You may have found something new.
