Simple F-Curves is an animation addon that provides a set of tools to automate and manage keyframes and curves without manual handle adjustments. It includes features to emulate the keyframe selection behavior of Cinema 4D and Maya, as well as an Armature Mode that automatically deselects keyframes when switching bones. The toolset offers utilities to extrapolate complex motions across multiple channels, add noise directly from the Timeline editor, and apply auto-bounce effects. Additional tools allow users to clean up unused channels, exaggerate curve shapes, smoothen sharp transitions, and shape keyframes across multiple selected channels simultaneously.
