Eye Movement: moves an eye based on the head rotation that should work with any general eye type.
Tail Physics: This will add physics to your tails when you spin, move, jump, etc. Has the option to have an idle tail movement, and can work with a tail with any number of segments.
Ear Physics: This adds physics to your ear(s) when you move, and has options for different ear types.
Crouch Animation(returned): Allows you to easily set a crouch pose, or crouch/uncroch animations, and even crawl/uncrawl animations/poses
Bewb Physics: This can add bewb physics to your avatar, which for some reason is also versatile for non-tiddy related activities
Randimation: Used to be known as squapi.blink, this will randomly play a given animation, most commonly used for blinking
Hover Point: Used to be known as squapi.floatPoint, this will allow you to have an object float naturally to it's normal position.(with optional experimental collision)
Vanilla Leg: This applies vanilla leg movement to a given object, but allows you to modify the strength of the movement and enable/disable it on command.(example use: legs under a dress)
Vanilla Arm: Like above, but arm
Bounce Walk: Makes your avatar bounce when they walk.
First Person Hand: Allows you to have more control over displaying your hand in first person, or even just having a custom element for your hand.
*Smooth Head: Smooths your head movement with additional depth added to it, squapi.smoothTorso and squapi.smoothHeadWithNeck have been removed, and instead these capabilities have been given to smooth head. You can input either a single head element like normal, or you can input a table of elements(for example torso, neck, head) and the rotation can be distributed between these.
(advanced)Bounce object has been replaced by BERP, which is cleaner and more consistent, and works with respect to dt.(also has been added BERP3D for 3d vectors)
