[Feature Request] Automatic Sleep Timer

[Migz93]

A sleep timer is already built in but an option that lets you set it to automatically enable whenever you play something. Every time I listen to a podcast I want it on a one hour timer, so just having the option to automatically enable when playing would be helpful.
I did see the option in the settings for "Stop playback after" which I thought might be an automatic timer but it doesn't appear to be.
