Nimble init doesn't support arrow keys
It's a minor bug, but when filling the form for nimble init, you can't use the arrow keys (to correct some typo for example)

- pressing Up prints "^[[A"
- pressing Dn prints "^[[B"
- pressing Rt prints "^[[C"
- pressing Lt prints "^[[D"

Possible solution: Nimble should interpret and handle these escape sequences, (left and right move the cursor, up and down probably shouldn't do anything, but don't print the escape sequence either)
