I've gotten similar feedback, re imagining what it would be used for. The simplest use case is probably the "shell terminal but better" one. You can narrow down the output of shell commands, and make reusable files with notes as you run stuff (for yourself to use later on, or for other people). You can nest the commands underneath directory paths to avoid having to CD. You can change parts of the paths to re-run the same commands in a parallel dir structure in a different place (even a remote server). You can search command history in a specific dir and re-run commands (vs bash history showing you commands that were run in any dir). You can post any notes you made on the web or email them to people, for others to help others get started using stuff.
