It's been 2 years since your post. Has there been any progress? This is one reason I do not want to install the app. There are tons of features and setting the app needs to work. And everytime I reset my phone, I need to send an entire day trying to get the old settings the way I wanted to. And every device is different in playing the kind of audio quality I needed. Why would not I get this feature when I'm paying to buy this app. I'm ready to shell out more money if this is what is required to get a full backup for the app. I do not think there is any other app other than Nova launcher and Poweramp that require so much of customizations and being left out without backup capabilities.
