Version 0.14 is out as well:
https://github.com/ruedigergad/Skipp...l.rpm?raw=true

In this version, I added a hack to control the media player volume.
Please note that I only tested it with the media player and that it may only work "reliably" when the music was actually started.
I also don't know how this behaves if multiple audio playback apps are active.

Please also note that, from version 0.13 on, the SmartWA watchapp support is enabled by default.
I don't know if this may cause any trouble.
If I find the time, I will add an option for enabling/disabling this but for now it looks like that I have to get back to other things.
