1. Currently there’s no way to move a block inside/outside of nested blocks which is a big missing piece. Cut/Paste can be a quick way to support this.

2. When I style a button block I feel the need to just copy the same button near it. Currently you can only add a new Button block from scratch. Copy paste can be a quick way to cover these kinds of needs. Button block is just an example but we'll keep on adding more style options to the blocks.

Copy/Cut/Paste is a popular paradigm so I feel like we can have a quick win feature here without needing to complicate the editor.

What I have in mind is just putting the copy/cut options to the new block menu we have. (The one that also has the Trash icon.)

Again if sth has been copied or cut, we could show options there like Paste after this, Paste before this.
