This is almost a deal breaker for me. Would love to use sidekick more often, but the inability to add an extra slide or edit a slide after the presentation starts is killing me. I’d love to have everything prepared perfectly ahead of time, but it rarely works out that smoothly.

To add onto this request - the ability to make on the fly edits like we had in version 1.0 for the wheels/voting/etc. would be killer.
