Open
Description
Add icons to the screen which allow users to 'react' to an idea; this might be similar to Reddit's up/downvotes, Facebook's reactions, or something entirely new.
This will require that a back-end API is reintroduced so that pairings and reactions can be persisted.
Reactions should be limited to one per person, perhaps using cookies or persisting a browser thumbprint. It shouldn't be necessary to require authentication.
