Love the addition of polls. Please allow us to link polls to other work item types like other ideas and features. This would be invaluable supporting data for why we work on the things we do.
I'm glad you are excited about polls and thank you for the helpful feedback! I have split this into separate ideas so that we can track them each individually. You can find the additional ideas here to vote on or leave comments.
Polls support playing videos (Animated gifs and video downloads are already supported)
Polls can have a comment thread
Poll questions allow an optional comment field
