Is there any documentation for themes? I’m wondering if the existing theme xml files contain 100% of the potential elements available, and for some, I’d like some detail about what the tag means so I don’t have to mess with it and import it to know what it does.
I have often wondered myself if other elements could be added. Unfortunately there is nothing beyond what is already on this forum.
The best place to start is https://forum.emclient.com/emclient/topics/custom_em_client_themes
