Do you mean, name it to a constant name, so that only a single file will be stored, because there is a replace option? That's a very clever and useful idea, thank you:) Still, integrated pdf viewing would be quicker anyway. From now on it would't be as crucial, but I would appreciate if Opera could add it during their spare time:)
Opera Mail uses the Presto rendering engine that was in Opera browser versions 7-12; they can't make Mail open-source without also turning over Presto.
