Animates Free Selects and Retimer
A set of free header buttons that facilitate a faster and more enjoyable animation workflow, alongside the powerful Retimer tool - an ideal pair to take control and speed up your editor workflow. As part of the Animates Suite, the header is the backbone foundation for well designed, deep and rich tools that perfectly compliment each other. Once accustomed you'll wonder how you managed your workflow without them, they allow you to stay in and focus more heavily upon working in the graph editor. The buttons are multi-functional and supply many precise and broad selections and manipulations of your keys. Simple yet powerful.
For Amp, Breakdowner, Smoother, Ease, Handles, Onion Skin, Editable Motion Paths and much more, check out the full Animates suite.

Animates started as a way to solve some of the simple yet crucial aspects of animating in Blender, in particular the ones my students frequently were bamboozled by - Sir, 'how do I retime my shot'. So here's my answer to help everyone else too.
I also love giving something hopefully useful back to the animation community ;)
I've put the same care into this free version here as everything else I build, and I genuinely hope it improves your workflow. Feedback is always welcome.
