Roadmap

This is just a personal project intended to learn Rust, so things move slowly.

This is a list of things I plan to do:

  • Add documentation (the rust way)
  • Refactoring (as I learn more Rust things)
  • Tests
  • Smart timestamp highlights
  • ... whatever I can think of when I am using it
