[FR] currently playing indicator for playlists

[owosoup]

Is your feature request related to a problem? Please describe. Ex. I'm always frustrated when I have to check the song queue to find out which playlist I'm listening to.

Describe the solution you'd like

I'd like for playlists to have the same indicator as individual songs have.

Describe alternatives you've considered

Instead of adding a motif, you could always render the font more intensely, or underline it, or put it in italics.

• [x] I will follow the issue format and will add [FR] to the start of my issue title, and I acknowledge that if I don't follow the format, my issue might get closed without further explanation.

Adding to this, a now playing indicator in the queue would be very helpful as well! :)
