Display the sleep timer if active

Whenever the sleeptimer is active, it isn’t shown. There’s just the crossed out ZZZ-symbol in the top right corner.
It would be nice to not only show the remaining time but also a fast to reach button to extend or stop the timer.

Best regards,

I sometimes use this Sleep Timer app in conjunction with the media player I am currently using as it offers the features you ask for

How does it look in terms of UI - is the timer shown?
