[Request] Hide when there's no media playing

[rosostolato]

It would be good to hide the widget when there is no media playing instead of displaying empty:

I have other idea for "no media playing" mode, I have described it in #15 - @rosostolato what do you think about it?

Just to jump on this... first off, great widget - big improvement on stock KDE. Impressed!

I would very much appreciate (being a systray clean freak) integration as a systray widget entry, or hiding when not in use through some other means if that is not achievable.

Systray entry would be preferable personally, since access would be v easy as a hidden icon and the uniform integration into Plasma would be very swish.
