Contribution
Feel free to help us!
Here are some issues to improving.
- Write tests
- Improve tui design.
- Show more information?
- There are no color in realtime tui now. I want help from someone who has some color sense.
- Improve speed
- I'm new to tokio. I think there are some space to optimize query scheduling.
- Mesasure DNS lookup time and dialup time.
- Add an option to disable keep-alive connection.
- Output like CSV or JSON format.
- Improve histogram in summary output
- It uses very simple algorithm now.
