Next update will include following features:
Auto kill music: If you have enabled quick settings in the app, music will be killed when you open the app and settings will be launched.
Splashscreen is removed.
Windows Phone 7 version will have ability to override music as in WP8 and will not require app restart in case of manual enable/disable.
Most important: You can enable/disable the settings you want on the volume bar. This will need an app restart though.
