 ## Default animations
 
-These are "ready to use" APIs that create specific animations for commonly used properties. They require little setup on the user side, with no need to deal with explicit property paths to animate. Examples of these are animations such as `Opacity`, `Offset` and `Translation`. Each of these default animation APIs also expose a number of overloads that can be used to easily customize how the animation is constructed. For instance by specifying a single translation axis to animate only using a single `double` value to indicate the initial and ending value for the animation:

Each animation type also supports using keyframes in addition to just defining the starting and final values.
 - **Activites** on the other hand are a way to interleave an animation schedule with all sorts of custom logic, such as triggering other animations or running arbitrary code (eg. to update a visual state while an animation is running).
 
 These two types of animation nodes implement several interfaces (such as [`ITimeline`](https://docs.microsoft.com/dotnet/api/microsoft.toolkit.uwp.ui.animations.ITimeline) and [`IActivity`](https://docs.microsoft.com/dotnet/api/microsoft.toolkit.uwp.ui.animations.IActivity)) which make this system extremely customizable and extensible for users as well for their own scenarios.

+Another feature of the `AnimationSet` type is the `IsSequential` property which configures the way top-level elements (animations, activities, and scopes) within the animation are handled.
 
 When this property is set to `true` each top-level node will be executed sequentially and only move to the following one when the previous completes (and the animation has not been cancelled). This can be used in conjunction with the various `IActivity` objects to create custom animation schedules that combine multiple animations running on different UI elements, with all the synchronization still done entirely from XAML. It is also helpful when combined with an [`AnimationScope`](https://docs.microsoft.com/dotnet/api/microsoft.toolkit.uwp.ui.animations.AnimationScope) in order to more easily parse the timeline of events within an animation when creating and modifying them.
