Save settings for shut down and app closed

[Lacolombenoire]

Hello, I am a mac studio m2 max user. I have successfully install background music. It is fully working and I really appreciate it.

My question is not about an issue, but a fonctionnality that I don't know if it's there.

I would like to actualy save the volume setting for all my apps and system sound when I shut down my computer or I close the application. Either when I do one of those things, Backgroundmusic rest all volume level of each apps to the middle of each sliders.

Thank you to anwser me as soon is possible.
