Sort of "Whitelist" useful for multimedia background-playing apps, navigation apps and many possible other

[NotesOfReality]

Dear developer, I would really like you to implement a kind of whitelist in which any kind of app could be included, for example a music-playing app like Spotify. If you did so I added spotify in the whitelist so that when Spotify is opened and I lock the screen Spotify wouldn't stop playing because of BatteryFu disabling the data. I hope to be clear, if I'm not please don't hesitate to ask for one or more clarification/s. Have a nice day!
