Option to hide votes could be more useful
When the option to hide votes until the user has voted is switched on, votes are initially hidden but are displayed as soon as any single choice has been entered.
Since it is usual to make several choices, especially since the tool doesn't disallow it, it would be more useful to hide votes for longer. Maybe until the end of a certain voting period.
What about hiding them until the talk is finished (if the end date has been supplied)?
That might work, although if that is how it works, I would configure in open-feedback the end datetime to be around 30 minutes past the true end.
Default value will be talk end time (easier to understand for first user) Optional value to add minutes for the results to be displayed.
An alternative will be to use the conference end time but I'm sure speakers want to see the feedback right after the talk ended.
