The (official, written by Brian Harvey) Manual. Reporting typos and/or updating requests

Generally speaking I like the new Manual, especially how the illustrations of Map, Keep, and Combine functions (on page 35) were updated.

And below there are some updating requests for page 58.

The problem is having this long paragraph about what Scratch does. The bit about how programs can't change the sprite's name is about Scratch. I'll fix this to be clearer.

I'm so pleased you like the new illustrations! Feel free to use them when you're teaching map/keep/combine to your students/colleagues...
