The editor

12 presets, in 3 categories

A preset writes real keyframes starting at the playhead, and you can edit everything it writes as soon as it lands.

PresetCategoryWhat it doesLength
Fade upEntranceThe default good entrance. Rises a short distance while it appears.520ms
Fade inEntranceOpacity only. The safe choice when the layout must not move.360ms
Pop inEntranceSprings up to full size with a little overshoot. Good for badges and chips.620ms
Drop inEntranceFalls into place on a loose spring. Reads as weight.900ms
Slide in leftEntranceEnters from the left on a spring, fading as it arrives.700ms
Slide in rightEntranceEnters from the right on a spring, fading as it arrives.700ms
Rise & settleEntranceOvershoots its resting place, then eases back — follow-through, by hand.660ms
Attention shakeEmphasisFour quick lateral beats that decay. Use for errors, sparingly.400ms
PulseEmphasisOne breath of scale. Draws the eye without moving the layout.500ms
NudgeEmphasisA single small tilt and back. Playful, cheap, hard to overdo.560ms
Fade outExitLeaves quietly. Exits should be faster than entrances.280ms
Sink outExitShrinks slightly as it fades — reads as receding rather than vanishing.320ms

Applied to several selected elements at once, a preset staggers them automatically. The offset comes from the motion system’s stagger scale, so there’s no number to pick.

Follow-through
Beside the stagger step, follow-through turns the selection into a chain: the first element leads, and down the layers list each spring is a little bouncier and a little slower than the one before. ζ falls by 0.08 and stiffness by 8% per link, never below ζ 0.35, so the last one swings furthest. A loosened final spring has its closing keyframe moved out to where it lands, so later elements finish later, and that overlap is intended. On animation that already exists, ⌘K “Add follow-through to selection” does the same.
Where follow-through stops
It loosens springs only. A fade on an easing curve can’t overshoot, so presets without a spring (Fade in, Rise & settle) are left as they are, and the stage says so. Each follower is loosened from the lead’s spring, so applying it twice changes nothing. It exports as what it is, every element with its own spring and start instead of one stagger, and the parity gate measures a chain in all three dialects.
