Feature description:

First of all, thanks for this amazing app. I just started with android, found this app and I am delighted. One tiny feature, would - in my opinion - greatly improve the audio book listing expierence.
There is already a play count available, but no option to manipulate it - other than actually listing to the song.

Problem solved:

By being able to either togggle an album/Song as played or unplayed (or being able to manually increas/decrease the play count), it would be much easier to keep track of the progress of audiobooks and downloaded podcast.

Brought benefits:

It greatly increases the usability for audiobooks, downloaded podcast.
Let me know what you think. Thanks for the amazing work.

There’s a button to reset playback history and so the play counts.

I’m not sure there’s enough needs to directly allow play count value manipulation as it also requires changing the last played date.
