Hi,
Thanks for reply. But your mod is an Estuary skin modified by yourself or just an additional addon that in combination with my Estuary will support Artist Slideshow.
In the former case my fear is that I will have an Estuary skin that will be overridden whenever I update OSMC (usually once every two months).
What happen if Estuary team  do a set of fixes to the skin? Do you back port them in your own?

It's technically a completely different skin with a different name and versioning.  It's just that about 99% of the skin code is Estuary, so it's called a skin mod rather than something else.  It won't be overwritten when you update OSMC because all skins (except the default skin) is stored is your userdata directory, and the skins and addons in your userdata directory are never touched during updates.  Any time the Kodi team releases a new version of Kodi I check to see if there were any Estuary updates and back port them to my mod.  Usually that happens within a few days, but for major releases (like when Kodi 18 comes out) it can take much longer.  And I do this in my spare time, so sometimes life happens and the Kodi stuff doesn't.
