Just saw that https://oxygenbuilder.com/documentation/other/multilingual-with-wpml/ was updated to state that initial conversations have happened between WPML and Oxygen. As most of my clients are from the german-speaking area and require German and English sites at a minimum, I would be stoked to see proper integration between the two.
Easy sites are easily translated. More complicated ones are a pain with Oxygen. Constantly running into issues. (Yes, I tried TranslatePress. Same issues.)
Consider this my official inofficial upvote for this feature!
