Hide file extension?

Love the app, but when I create new files, by default the .scriv extension is always visible. Could you add an option in the preferences to mark the extension as hidden? (The Finder option to hide file extensions has no effect on this; I have to Get Info and manually check the Hide FIle Extension.) I really don’t want to create a Folder Action that does this via scripting.

Otherwise, I love the app. =)

Scrivener 2.0 will just use the regular save panel to create .scriv files, so hopefully this won’t any longer be an issue.
All the best,
