This is closely linked to the "Invite participants" feature.
Ideally, I'd like to be able to have a contact list that I can maintain (just name + email). Later on, I could even organize them into groups: "colleagues", "board game friends", "tennis club", etc.
When I create a poll, I can directly invite people from my contact list to participate in that poll.
This would be very useful for people who often organize activities with the same groups of people.
