Yes, a screenshot would be good to get a visual on this.
I have done a simple shell using Rustyline and Clap and this could be something I might be interested in but it's hard to say without a visual idea, asccinema would be perfect!
asccinema is a killer idea! but I am still chasing my perfect shell . If you end up implementing an insane looking shell with this, contributions are always open.
I don't have the time to look deeper into it right now as I am quite happy with my current setup but if you do want to make an ascinema recording here is a little tool I wrote to help testing and recording CLIs
