Hi there,
with the latest update I didn't have the issue where the skins changes back after three seconds anymore. For those having troubles to edit the menu: I used the following workaround:
I assume you all come from Kodi 16,
just do all the modifications you want to to on the menu and then export/save the settings to a file.
Just remember that you save this file to a filesystem that will not be overwritten when you do the update
After you installed the Phenomenal Skin on Kodi 17, you import/load the settings from this file.
For me that helped, I have the same menu structure as I had on Kodi 16.
Some issues I have: I'm running on as RPi2 with LibreElec8. If I start the LibreElecSettings programm it doesn't use the PhenomenalSkin layout, but the default one.
Normaly I saw a preview of my video lib on the homescreen (Fanarts). This doesn't work anymore.
Thank for the update and your work
