I wonder if it'll be good to go from a line-by-line print to an actual TUI. That'd make sorting + dynamically inserting new domains make sense
I’d be fine with a live summary status updating showing # available and # taken. Hitting ctrl+c resulting in printing the lists as above.
Also perhaps a —timeout flag, or similar as I may only want to wait 5 minutes / length of time it takes to steep tea for answers.
