At any time you can use the Replay button to allow you to see how the Wave unfolded, every edit is recorded by the system. This allows you to see what changes you or another person has made to a blip by following the flow of time.

Press the Right or left arrows to move forward or backward in the wave timeline you can see how far along the time line you are with the time line indicator, you can exit the wave playback by using the X at the far right side of the time line indicator.

Note that even if you delete a blip you created or someone else’s blip it will still appear in the replay up until the point it was delete
