[UI] Rearrange UI's panels isn't saved on exit

[brunetton]

System information

Ubuntu 21.10 (impish)

Detailed information

Moving "panels" (not sure this is the right term) around is a great Qt feature to allow users to rearrange UI to feet our needs ! But I'm not sure that this is something really wanted in Spotify-qt, as there's only one panel that can be moved around: the current track's information:

What happens?

• move current track info somewhere else than its default position
• quit Spotify-qt
• launch Spotify-qt again
• => the panel is back again to its default position

What should happen?

The panel should be at the position it has been moved before exiting the app

Maybe the fact that this particular panel can be moved around is not a wanted feature ?

Thanks !
