Auto switch from now playing to selected track details

[Lore]

Hi,

Not sure if it is implemented and I'm missing the option but I'd like the following behaviour for track details panel:

- If a track is being played, show details for that track;
- When no track is being played, show details for the currently selected track.

I hope it is clear, basically this switch is manual (by clicking on the panel header) and I'd like it to be automatic (possibly through an option).
Thanks and regards,
Lore
