It looks like the animation editor no longer allows developers to rename keyframes? I was looking through screenshots I posted on a previous thread and found that keyframes used to be able to be renamed here:
but it doesn’t seem this is still the case. The option is missing from the context menu, and I’m not seeing it anywhere else in the UI:
Why was this feature removed? I had plenty of times where I needed to rename a keyframe and I always was forced to rename it manually by editing every Pose instance.
The feature wasn’t removed, I believe its working. You just need to right-click the row that has the name of the rig you’re currently animating (the white diamond) and the rename option should show up.
