[Xposed Framework Modules] aLexzkter:
If it's a notification sound, why can't I override the sound with one I choose on gravitybox's ultimate notification control (per-app settings)? Overriding notification sound works with Whatsapp, for example, just tried it.

About the led issue, cleared xposed logs and tried press&hold home key for play/pause chain. I wasn't using any player at the moment.

Black theme looks beautiful, huh? :)
