Maybe I'm stupid, but for now Master Styles only save font-related properties. Changes to Transform are ignored. Especially maddening with subtitles, when position and scale was used initially, and I now have to go back to every single one to reset those, because there is no way to do that via "remove attributes". Why add a transform property to text but then not make it (an optional) part of master styles if there is already a motion property for the whole layer? (Which I can copy over different layers...)
