Thanks chewitt - is it the case currently that whatever skin you have activated, you see an Estuary-type experience when you are within this addon?
From a brief look at the service.libreelec.settings on github, I'm guessing that the styling is actually dictated within the addon in the resources/skins/default folder and that this has a similar look/feel to Estuary as that is the default Kodi skin. As opposed to pulling settings from a skin itself. https://github.com/LibreELEC/serv…s/skins/Default
Thanks for the info re. GUI development, I'll keep this in mind for the future.
