Add Ability to Use Output from a Previous Block in a New Command (re-pipe-able blocks)

(from youtube comments)

Also, the history should be reference-able and pipe-able, so I could pipe output of one of those blocks into some new command - this would make these blocks actually useful.

Not sure exactly how to do this and what the implementation could look like (is it just the text from the blocks, or should it include the formatting, or should it replay the entire pty stream with ANSI escapes?). But the concept is interesting and something we can do. Being able to reference a previous block and pipe it into a new command feels powerful.
