Screen Space Tool makes object tracking absolutely easy. Highly recommended for Tracking! 

These tools will make you look like you know what you're doing!

The ScreenSpace tool has saved a ton of time with dynamic object tracks & roto animation. The team here uses it religiously! 

eblabs tools are great for animation. The motion trail tool is the best I've found. It's fast and efficient allowing for a much quicker workflow. I'd highly recommend it.

whisKEY is a must have tool for character animation at the blocking stage!

eblabs suite of tools are invaluable to my work flow, I bring them with me where ever I go! Thank you Eric!

whisKey toolkit is an indispensable collection of slick tools that consistently saves time and headaches, I highly recommend it to anyone.

The underlying code is clean and well thought out, which makes the toolkit's functionality a breeze to integrate into your setup.

A couple favorites include the worldSpace and screenSpace tools - along with the rest I believe they will make as great an addition to your toolset as they have for me!
