Heh, that’s what I do, think and dig when I think I might have a use for something. Unfortunately I don’t have much free time either. But I’ll be keeping this in the back of my mind for a time when I could be useful. I build plugins using ACF and this could be a way to allow one to be extended. Usually the first opportunity I get to put the research time against a paying client is when I really dig into stuff like this. 🙂
