Love this! It's helping my dev and design teams align more easily. A doc page somewhere explaining the syntax would be helpful. But at least be sure to read the json example on the extension's page in the chrome store. Especially note that the gutter width parameter is HALF the full gutter width. I sometimes see the error that the JSON isn't valid, even though it passes in online linters. I refresh the extension's options page and then save it again--the error goes away.
