Gradle userguide structure - orphaned pages?

Hello, since gradle 4.5, the documentation structure changed obviously, as mentioned in the release notes (https://docs.gradle.org/4.5-rc-1/release-notes.html#documentation-enhancements):

https://docs.gradle.org/4.4/userguide/userguide.html
https://docs.gradle.org/4.5/userguide/userguide.html

To me, the 4.5 page seems more unclear than 4.4.
For example, I know the url (https://docs.gradle.org/current/userguide/tutorial_using_tasks.html), but if I was a beginner, I would never have found this useful page.
I couldn’t find any navigation to that link except for addressing the url directly, and this is not the only page that I cannot find currently.
Are these pages orphaned now, or are there are (well hidden) links to them?

Thanks
Jan

@eriwen this might be of interest to you

There are a few pages that are intentionally left out of the left-side navigation, but the Build Script Basics chapter shouldn’t be one of them IIRC. That is my oversight and I’ll fix that.
