Todos

• Introduce rich-click
• Import top-level click in all files
• Switch click to rich-click imports
• Read documentation to understand the majority of aspects of this lib
  • Set SHOW_ARGUMENTS
  • Group and sorting
  • Set MAX_WIDTH? No, since if the width of the terminal is smaller than the set value, then it’s no longer responsive and take the value set not lower.
