This element was added some time ago:
<element id="NowPlayingPanel.SpectrumVisualiser" fg="30,255,255,255" fg2="30,83,91,18" />
I can't find how or where to display this. I would think it should be the one in the left panel?
(but that doesn't change, that's why I'm wondering)
@ Bee-liever: Maybe you could you help me with this? (since it was created at your request)
