Also, not sure if it should be better to open another issue, but I'd like to see a button to go to the source code directly as in the angular.io. Sometimes we need to take a look in some implementation and we have to do it "manually".

Just a heads up that we kicked off a community voting process for your feature request. There are 20 days until the voting process ends.

Thank you for submitting your feature request! Looks like during the polling process it didn't collect a sufficient number of votes to move to the next stage.

We want to keep Angular rich and ergonomic and at the same time be mindful about its scope and learning journey. If you think your request could live outside Angular's scope, we'd encourage you to collaborate with the community on publishing it as an open source package.
