Just a friendly suggestion since I did not see this in the shortcut keys list. I know you can shift+click a point in the sprite to set all frames in the animation with the same origin point location. You can also use number-pad keys to move the origin point around, but just for the current frame. I suggest adding a mix of these 2 auto features of origin points by adding a shift+numberpad key combo to auto-set all frames of the animation to a specific location as well. For example shift+7 would move all frames' origin point to top left...shift+5 would move them all to center. I'm working a lot with origin points at the moment and it would have been a great extra time saver. Thanks for reading!
