In Fargo 0.71 there's a new Settings panel called Code, with a place to enter JavaScript that runs when Fargo starts up. Screen shot.

Note of caution: If you're a programmer, be careful. If you're not a programmer, be much more careful. This is potentially a very powerful feature which means it is also potentially a very dangerous feature.

Be sure you know what the code you're entering does, and that you trust the person who gave it to you. When in doubt, don't.

With that caveat... we look forward to seeing what people do with this feature.
