Lazy KeySet gives Blender animators a set of tools for building simple, motion graphics-style movement with a few clicks. Its Stepping function moves the selected keyframe in steps, and Use Selection Order adds an object name list so steps can be created in the order you want. Blender has no selection order, which this addresses.
Sync Key Tools handles key editing without going through keyframe selection on the dope sheet, working on the current frame or a specified range. Editing a bone with the same name as a shape key lets you edit shape keys indirectly, and the Create bones with shape key names function builds those matching bones all at once. By default a rotation Z value of 0 to 90° maps to a shape key value of 0.0 to 1.0. The panel appears in Pose mode under the N-panel, with an Alt + Shift + D pop-up.
Set a Keyframe Between 2 Points inserts keyframes with animated position, rotation, and scale. You can set the animation interval, delay, keyframe interpolation, and easing, including a Special Ease In/Out option that corrects the F-curve handle for a strong ease. It supports Blender 2.8 through 3.5 under the GPL license.
