Pages with the same name in the MS4 handbook

You mean https://musescore.org/en/handbook/4/palettes and https://musescore.org/en/handbook/4/palettes-0, I guess

Good point! I tried to avoid that where I could, but obviously missed this. I'm thinking it might make more sense to rename the Basic s version, though, to something like "Using the palettes". That's more consistent with some other pages in that chapter that use verbs, whereas the Customization chapter pages are all just nouns. I might also consider verifying some other pages in Basics, like changing Voices to "Using multiple voices" or even "Using independent rhythms on a staff".
