It would be nice to have a feature that allows you to hold the screen whatever you are projecting, and let you to change on the fly inside the timeline.
For example, I had one situation that in the last minute one of the speakers couldn't assist and it was substitute by another. The client notified in the very last minute, and I need to add more layers in order to add the new person. I could do it, adding this in a new sequence, but it was impossible (I used all of the them, MANAGER STD). So I couldn't change this on the fly, so I had to ask 5 minutes to the client to stop, in order to make this change.
I know that Watchout has this feature, and if I remember is call Live Preview
Hope you understand me properly.
Thank you.
