Using a modal to enter content rather than changing the designer panel. We ended up extending the designer panel to accommodate entering content and uploading images.
Trying to solve the problem of corresponding text and images. We ended up having the text and images separate but in a default order. For example the first answer in designer is the first answer on a poll.
If a user has to select the poll layout in advance, they lose flexibility. We ended up creating a toggle within designer so the poll type can change.
