How can I edit snippet?

I couldn’t find a way to edit saved snippet. How can I do that?

Snippets are immutable for various reasons. You can fork and save it as a new snippet then delete the old one.

If I delete snippet and create a new one, snippet link changes. It is a big problem if I’ve already published that link to some sites or sent it to others.

It would be great if we can change at least the visibility, title, description, or maybe redirect feature.

You are right, it will be a problem. But you need to make sure the snippet is ok before publishing anywhere.
