To-do

General

• Saving and loading user data is fragile and subject to memory leaks. The current implementation is quick-and-dirty and "works" fine, but needs to be more robust.
  • Promises inside useEffect hooks need to be refactored to avoid memory leaks.
  • Data storage options beyond local browser storage should be explored.
  • Currently, the code probably doesn't scale well with large amounts of data.

See the pairing & scoring TODO document.

User interface to-dos

• Overhaul the pair-picker view. It should show more information about potential pairings and have a preview & confirmation for the auto-pairings.
• Improve responsiveness across devices.
• Improve accessibility.
• Implement drag-and-drop to supplement buttons.

Low-priority stuff

• Add round robin pairings.
• Improve rating calculations: add provisional ratings and possibly move to a different engine (e.g. Glicko-2).
• Pairing and scoring: improve potential compatibility with third parties.

Test coverage

• Test that there is only ever one dummy player per round.
• Test that removing a round resets all of the matches within the round.
• ... lots of other stuff to reach 100% coverage. Tests currently only cover a few of the most fragile functions.
