Some non-blocking suggestions

[cbullinger]

possible to get this on multiple lines so it's easier to see the multiple sorts? something like:

Suggested change

	auto sortedListProperty = specificProject.items.sort({{"assignee", true}, {"priority", false}});
	auto sortedListProperty = specificProject.items.sort(
	{{"assignee", true},
	{"priority", false}}
	);

I wasn't sure where exactly to split them and where to put the brackets per C++ convention, so I've configured my VS Code to use the Google linter for C++. It has a default line length of 80 characters, which is the same as our docs line length limit (ostensibly - we don't apply it particularly stringently). But I don't love some of the other formatting changes it made, so I may experiment with linters going forward to find the best one.

It's a good suggestion! We should probably be setting a line length for all of our code examples across all of our SDKs. A lot of mine scroll out of the visible area. I'll add that to our sync doc for discussion.
