That'd be really cool. I'd never thought about enabling deeper graphical capabilities in a shell. But if you were to have a shell with rich objects rather than dumb bytes, that is a world that would open up!

PowerShell, for instance, has Format.ps1xml[0] that allows you to configure how objects get displayed by default (i.e. when that object gets emitted at the end of the pipeline). Such a concept could in principle be extended to have graphical elements. How cool would it be to have grep's output let you collapse matches from the same file!
