I escalated the feature.

Was this feature ever added since the 2013 request?

I like teh ideas and added as http://www.ventismedia.com/mantis/view.php?id=11665

The sleep function in MMA has an option to play the last track completely before stopping. It would be useful to expand MMW's sleep function with this option, and another option to sleep at the end of the now playing list instead of being time based.

This isn't exactly what you asked for, but see in the menu: Play --> Sleep

Please add an option to exit after current song has finished playing.

Thanks
