Transitioning elements is a core feature of the Graphics production world.

The Transitions Engine lets you orchestrate the entering and leaving animations of every element inside Overlays and take your Graphics to the next level. This is available for every new Graphics Package you make, but older ones require you to manually activate the new Transitions Engine.

(1) Just head up to the Graphics Package properties on the Inspector Panel by clicking on All scenes, and enable the "Use new Transitions Engine" switch.

(2) The new Transitions Panel will appear below the Canvas.

You can collapse it and toggle it back on when you need space.
