2. An option to insert "last inserted keyframes". If you've inserted an action which includes several keys at different layers and you want to hold this pose for 7 frames, then it's very time consuming to find all this keyed layers and insert them again at another frame, it would be great to be able to step forward 7 frames and use this "Insert last inserted keyframes" again, I know you can do it with the script: "Key all" but maybe I don't want to key all channels at this point, I just want to key the last keyed channels.
When working with "Blend Morphs" this would increase the speed a lot.
