Issues with The Tutorial Super Rentals

[welja]

Hi, I am just starting to learn Ember and though i like the tutorial soo far i do have a few issues.

1. Explain how to debug. For some reason (still have not figured it out) when i added the routes/index.js the demo site only displayed the gray background. All the content was missing. Eventually (using another tutorial) i used "ember generate route index" and it suddenly worked again.

2. I like the inclusion of the unit tests, but they are a bit too much. A simpler test at the start to show the idea and maybe a whole chapter later on would be enough. Now they are adding too much extra info.

3. Don't use examples where you need a login for a service. It's annoying and resulted in skipping the whole page. (have i missed something important now?) ( https://guides.emberjs.com/release/tutorial/part-1/reusable-components/ )

4. I like the codeblocks with the diffs, but an option to just copy the new version would save a lot of time.

Just my two cents! Now back to the tutorial :)
