But at least at the time (~2 years ago IIRC), the support was really basic, just basic record display, and most importantly, editing the parts VD didn't understand lead to data loss. I don't remember what I was trying to do - the error report I wrote with those details died with my old machine - but it wasn't anything too complicated, just array fields and foreign keys I believe i.e. just using recfile features one step beyond a listing of `key: value` pairs. I gave up on recfiles as a whole after losing data a few times like this (since I hadn't found any other suitable tool either).
