Animazing - Animation Tools is a feature-packed addon for Blender that gathers a range of animation tools aimed at eliminating common hassles and streamlining animation work. Rather than a single effect, it collects several utilities under one addon, each targeting a routine part of the animation process.
Root Bone Reverser reverse-animates a character's root bone automatically so the character stays in place, and the result can be exported with the 'Only Deform Bones' option for use in a game engine. Auto Frame brings the active curve into view and zooms to the segment you're working on, while Animation Scrubber lets you move between keyframes by moving the cursor, with a 'Sensitivity' slider. Share Keyframes copies keyframe timing from a source bone to other bones, and Precision Transform adds dedicated buttons for precise transforms on different axes. Timeline Arranger organizes the timeline to the length of the selected animation with a single click.
Documentation is included, and a demo video is available covering the 1.1 update.
