How to modify a skin (Specifically Estuary)

I am recyling some info I had from Confluence (Kodi 16), to see if I can add the “Time Remaining” field under Estuary (Kodi 17) and have failed at the first hurdle.. Could someone help me?

I am running a LibreElec system on Pi, and by default the “Esutary” skin lives under:

/usr/share/kodi/addons/skin.estuary

I copied the entire directory to:

/storage/.kodi/addons/skin.esutary.jon (NB. I renamed it to .jon in this step)

I then edited the ‘addon.xml’ file and changed it from:

<addon id=”skin.estuary” version=”1.9.10″ name=”Estuary” provider-name=”phil65, Ichabod Fletchman”>

to

<addon id=”skin.estuary.jon” version=”1.9.10″ name=”Estuary Jon” provider-name=”phil65, Ichabod Fletchman”>

But after this step, it does not appear in my list of Skins.. Just to double check that I have the correct directory, I downloaded a random skin (Amber), and now its in my Skins list, i can also so it in the directory on the filesystem:

drwxr-xr-x 10 root root 4096 Mar 1 12:16 skin.amber
drwxr-xr-x 11 root root 4096 Feb 28 18:31 skin.estuary.jon

But my “.jon” version of Esutary skin never appears in the list. Is there something else that needs to be changed to allow Kodi 17 to see a skin?
