Score each roadmap item against the criteria together. Click a score to cycle 1 to 3, type to rename an item or criterion. Everyone sees changes within a few seconds and rows sort by total.
Scores are saved on the host's laptop, so this page needs it to be running. Ask the host to start it and share the current link. If you were given an address, open this page once with ?api=https://the-address on the end and it will be remembered.
