That's another made up point not coming from the source. But also, that's almost literally what they did. Ok, it wasn't in a week but a few months and the % is not 100%, but still more than 50% But then this project's first release was in Feb, so it's actually been longer in development than the brew UI app! It's not a 1-week app! Stop making hypothetical stuff up, look at real apps
This isn't just a replacement for the homebrew UI, it's for the CLI too, so comparison invalid. I see the dev behind it has a whole 4 years of github experience - only the most recent 2 of which with anything significant (presumably model written), how reassuring.
