Stationery Pad is a handy way to nix a step in your workflow if you regularly use document templates on your Mac. The long-standing Finder feature essentially tells a file’s parent application to open a copy of it by default, ensuring that the original file remains unedited.
Follow the link for a way to set any file on your Mac to be a template file, so you don’t overwrite it. I don’t feel bad for not knowing about this trick, since I’ve never heard it discussed, and since the name doesn’t really describe what it does. On the other hand, I feel stupid for never wondering what that checkbox does. This will be very handy for automation tools like Keyboard Maestro.
