This seems somewhat expected to me. If you use the formatter for the project, you'll get the same results (once the line reaches 140+ characters, it'll not inline the array). I wouldn't want to inline all of those imports onto one line. Nor would I want to claim that the whole line has changed. We're only adding one extra import.

We don't include this branch in the academy, but here's the branch that shows the imports diff as one line: bitovi/angular-ngrx-chat@ngrx-init-feature...ngrx-init-manual-changes

I think that we could avoid some confusion by mentioning that we have a formatter installed as a dev-dependency and you can -instructions on how to format- to view the same results

I've landed on trying to explain how to use prettier~

I've added a part explaining prettier: #354

Not sure if this makes things clear enough though. I'll get my eyes on this section for further feedback
