@steffinchen I just realized, that the README.md has an incorrect reference to running e2e tests. Can you replace npm run e2e with npm run e2e-dev in the README.md file? Other than that, this MR looks super good to me, thanks!

@steffinchen I stumbled upon https://www.youtube.com/watch?v=gCKjsd4gaxI&list=WL&index=1 and suggest, that we use these new checks as well in this project. Do you agree?

I agree on making use of Angular Extended Diagnostics. Enabling such tools, usually required some none trivial clean up/refactoring. This is scope creep for this PR. So, please do so in a PR of its own.
