New filename input field in the navbar

[twocow]

An input field that accepts a string and redirects to https://example.com/string/edit so the user doesnt have to edit the URL in the address bar.

The space on the navbar is limited, but what about a popup when someone clicks "New"?

I think a CLI flag for 'show a prompt when clicking new' would be a reasonable way to do it (and a good first issue for someone with a little JS familiarity).
