Comment 8 for bug 1522939

What I've learned is: if every skin-wide occurance of i.e. [SkinName],show_something has persist="true" attached, it's value will be stored in mixxx.cfg.
Some controls might be temporary on purpose (like show_skinsettings or hide_mixer) if the skin designer want's this to be the standard view when reloading the skin or launching Mixxx.
So, basically every setting can be made permanent but the skin designer has to decide which should and which should not.

For lp:1531990 adding currentpage="[CoverArt],current" to <WidgetStack> should help, right?
If yes, I would tackle that bug(s).
