New in Keystone 3 - Revamped Stagger features

Keystone 3 - Modular interface and new section shortcuts
Save a LOT of time
Manipulating keyframes and layers takes a lot of time when done natively in After Effects. By using Keystone just a few times a day, you will easily save several minutes per day, an hour per week, and several hours per month.
The more keyframes and layers you use, the more time Keystone saves you!
Keystone 3 - Save a lot of time with Keystone extension
Complete overhaul of the Stagger and Distribute functions
Staggering is one of the most widely used techniques in motion design.
With the new Bezier controllers of Keystone 3, say goodbye to boring linear staggers and distributions and take your animations to the next level. On top of that, 3 new modes make it more intuitive than ever.
Keystone 3 - Keyframe and layer Stagger
Other tools can’t. Keystone can.
After Effects is notoriously known for breaking easings when you move keyframes, and other third-party tools on the market don’t do any better.
Keystone is the only tool that performs the necessary calculations to preserve your carefully crafted motion curves.
Keystone 3 - Easing preservation
Align your tangents and keep them aligned effortlessly
A user favorite since Keystone 1, the "Constant Speed" feature takes away the struggle of aligning tangents by hand. Best of all, these constant speeds are preserved when using any other Keystone 3 function.

Link / unlink keyframes and layers
The "Link" options are arguably the most underrated feature of Keystone 3! They unlock a whole new level of keyframe and layer manipulation, enabling you to link or unlink them in ways that are impossible natively in After Effects.
Keystone 3 - Link or unlink keyframes and layers
Up to 3 modes per function
Easily accessible with shared hotkeys, modes let you control how keyframes or layers are grouped together.

Below is an example using the “Align to CTI” function:
Keystone 3 - Layer mode, Property mode and Global mode
