Show HN: I made a quiz to help people learn Claude Code features (with macOS UI)

I also went a bit overboard on the UI.

Some of the backstory:

- I'd seen Boris's X thread of lesser known claude code features

- I taught two of my non-technical friends some claude code features in person recently (I did a few AI tutoring sessions with friends, for fun and curiosity)

- In the process of teaching others, I consumed some of the official educational content from Anthropic

- I saw how many not well known features there are!

- With a lot of Claude's help I made this.

- The UI scope expansion was very fun to indulge.

Let me know what you think!
