Here is the part nobody tells you

Two of those six were not hypothetical. They are handlers you have already built this week, block for block, in your own Digital Doodle app.

Round 6 — the photo appearing

You did not build a toy version. You built the actual thing. The apps on your phone are bigger, and there are thousands of these handlers instead of four — but it is the same four ideas, all the way down.

Your turn3 MIN

Pick any app you actually use. Name one thing it does, then write the handler that would make it work. Component names do not have to be perfect — the shape is what matters.
