Graph Generator

Works well. It does not have an uninstall button, so updating can get confusing if looking to 'drag-and-drop' from extensions page. Have to turn off the old one first.

Agreed. There are some funny stuff happening when working with slotted actions and armature keys sharing frames.

Even if only one object/bone is selected and only that one's set of keyframes is selected (dope/action/curve editor will now show summary keys + actual keys as selected), if the user presses save keyframes it saves every keyframe under that keyframe column (even even the ones filtered away for "selected" and "slot" in the action/dope/curve editor.) So if you've for one action slotted in several meshes, bones objects, shapes etc., timed to the same key you unintentionally get tens to if not hundreds of saved channels.

E.g., if 3 bones are loc rot and scale keyed for one column in the same slot/action, you select one of the bones and select only that bone's summary keys which again forces the implicit selection of the entire action's summary keys you will see 27 keys being saved instead of the expected 9.

However if you in the action/dope/curve editor drop down the bone's individual channels and select them individually the addon acts as expected.

Exceedingly useful addon though, and great help on the way to attempting to automate character locomotion in scene.

Quite useful for secondary motion, try it out!
