Including a nifty ability to sort lines by a user-definable column.
Oh, and the ability to run a `jq` command on a JSON buffer to whittle
it down, which seems to be very data-centric.
I liked my piper idea, but I just used it so seldom. Instead, I feel
like the ideas could be integrated into a data-focused function
collection. The interface is actually more dynamic and I can use it
without the "Piper" interface.
