This isn't getting pushed until AmandaC's tested it. I'm not sure this is such a good idea, anyway ; if it's for load/save workflow improvements, wouldn't it be better to have a file access method that allows for file re-opening? That said, there's a limit to *that* before you just have to say, "Just use /data/".
