- [ ] 1. Heap sort and shell sort, so all six classics can be raced side by side
- [ ] 2. A race mode: run two algorithms on the same array at once, two canvases, two counter pairs
- [ ] 3. Sound: a tone per comparison whose pitch tracks the bar height, with a mute toggle
- [ ] 4. A time bar chart of comparisons/swaps per algorithm, accumulated over runs
- [ ] 5. Save and share the array via the URL hash, so a specific run can be replayed
