To me this is just more of the same: added convenience to what we already have. Converting individual commands to TUIs is a step away from the unix philosophy.

I think the future of the command line lies in the direction of flow-based programming and spatial representation of complex commands.

I would like to see a terminal that, as I type, _generates_ a flow-based view of my command. Every command would be visualised as a component: ls, awk, sed... Every |, < or > that I type would append a link and a new component to my flow, and ultimately I would be able to manipulate my flow instead of typing: click the ls component, have it output Creation Date instead of Modified Date, then click the awk component and add another output to a new sed component and so on.
