Thanks for the comment! Yeah, I hear you. awscli is really awesome tool, but when it comes to day-to-day/adhoc operations, it doesn't do well like Unix tools. And that is exactly why I wrote this!
I wrote a similar tool for Digital Ocean a couple of years ago, for the same reasons! Improving CLI UX is shooting fish in a barrel, few designers seem to care about the non-web experience.
Yeah, right. Quick and dirty CLI experience is a bit different from fancy GUI!
