You're not really looking at the whole map in-game, but the screenshot is super helpful for planning. Also, Android and iOS supports pinch and zoom so you can see pretty much the whole Farm or even Town map that way, too. And that's available in-game so is really helpful, especially with the smaller screens. I'm assuming the Switch doesn't have that option, but it really should as many tablets have bigger screens than the Switch, but can zoom all the way out.
