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.
  • Output like CSV or JSON format.
  • Improve histogram in summary output
    • It uses very simple algorithm now.
