Hello,
big +1
I just discovered that copying a key from one bone to another isn't not implemented yet. Huh...
Are you planning to do it any time soon?
Originally I wanted to duplicate a bone with animaiton... Then I've found out that it duplicates just the bone, but not the animation. Then I wanted to copy the frames to save time, and ooops I cant 😃
It's quite tedious to do it one by one when there is multiple objects... I would say this feature is kind of a must have, I'm quite surprised that it's not there... 😢
