Add Sync Playback to Display toggle buttons to Custom Commands. I want to know if this is possible I was thinking probably it might be through http commands but that is to complicated for me would appreciate if some could give a walk through.
You need to ask on Kodi forum the JSON Command or built in command then I can tell you how to add it to Yatse 
If there’s a command then it’s possible.
Thanks I was hoping I just could not find it in the kodi wiki. I have asked in the kodi forum if it is available if not I will need to convince the developers to add it.
