Where can I find my downloaded pictures?

- In the Downloads folder on your computer;
- in the Files/Downloads or iCloud Drive/Downloads app on your phone.

What does the New Layer button do? I clicked and nothing happened.

You can now draw on top of the existing drawing without creating secondary connection lines.

Where is the Undo button?

This feature doesn't exist yet. In the meantime, you can use the Eraser. You can change its width using the Eraser Width tool, just like you did with the Brush Stroke. Don't forget to click the Brush icon when you're done.
