This looks pretty cool. I actually spend quite some time thinking about something like that. I came up with two things that I'd add to a shell : graphics and links. Graphics you did. It seems that is doesn't degrade gracefully though, like programs that do colored output disable it when run non-interactively ?

I imagined links as something which when activated would be pasted in your command line. For example when running "git status" I would be able to get a ready made command to add a file by activating the "add" link next to it. Each file name would also be a link so that I don't have to copy/paste it. Ideally, links could be triggered with keyboard shortcuts to avoid using the mouse.
