@maraino I've tested this out with various flag combos, seems to work well.

[maraino]

Looks good, but I would move that method to init.go.

I can also see if I can made ui.Println to support options so we can do things like

ui.Println("What's your name?", ui.WithValue(ctx.String("name"))

OK, I've addressed your feedback. The version with the options would be nice to have. If you want to do that, please add it. Or just approve and I'll merge :D
