This reminds me of https://github.com/mooz/percol

Percol was actually a source of inspiration as well, but I got tired of typing things like:

git checkout $(git branch | percol)

Since I had to almost compose my command beforehand rather than decide once I saw the output. So we take the opposite approach. Great UI though!

Does fpp support history for its command prompt? With the percol approach, you can easily re-run the same command with a different selection.
