You can zoom in and out the timeline in Wave.video to make the editing process more convenient and precise.
The feature can be found underneath the timeline on your right.
It is especially useful when your project features multiple scenes with different elements such as texts, graphics, stickers, etc.
Zooming in the timeline will help you arrange the objects more carefully relative to each other.
And when you want to see your project as a big picture, zoom out the timeline.
