Good.

That would be a good change, yes, please.

Hmm... I'm not sure it's an improvement over the simple
"y/n/N/e/?" prompt.  For completions and other cases where the total
text is too long to fit on a single line, such a dropdown-list can make
sense, but for this particular case it just reminds of me people using
tons of different typefaces in Word document.
