I don’t know, nothing struck me as new, the only difference is the presentation and the mouse (but I prefer keyboard). the example given for animated indicators already exists using ASCII escape codes. my zsh already has syntax highlighting on the prompt indicating mistyped commands, and suggest possible completions with a tui (with vim bindings). I could go on but anyway my point is everything they show is already possible with a tui, the only reason a clicky clicky solution doesn’t exist is because keyboard are freakin better and faster. They are right that we need a terminal evolution/revolution, but it’s not the mouse.

Maybe the author has a specific use case, but this seems completely silly. If you want to choose which OS to boot remotely, why not ssh in the machine and change Grub’s boot order for next boot with grub-reboot? Make the default boot be a minimal OS exposing ssh. You could even have the ssh server in initramfs with dropbeard / tinyssh, no need to fully boot an OS.
