But you've got to admit that OPs tool does it quicker, except if you like to memorize flags or already have a script specifically for this. And it's much nicer on the eye than most (all?) nmap-guis out of the box.
The goal has never been to create something that can replace nmap, the goal was to learn more about networking and about building TUIs in Go. Honestly I am quite overwhelmed by the amount of traction it got today, definitely not what I expected.
I am very grateful for all the feedback and suggestions, and I will take my time to evaluate every comment. In the coming weeks I will try to implement most of the feedback and do releases to improve the tool further, thanks everyone!
