This isn't exactly default, or known, in forum polls but hey, we're all about forward thinking. A lot of poll options, especially open questions, have an Other option. I figure it'd be nice if the Other option creates an input field for the user to specify their own view. This can then either be added on to the poll as an extra option, or just logged for the poll starter to view. It's just something that crossed my mind when making a poll earlier.
