Why is eclipse removing the navigator view?

Building off of nitind and osoblanco’s suggestions: You can make Project Explorer look exactly like the deprecated Navigator view by the following steps:

1. Click Window->Show View->Project Explorer
2. Click the three vertical dots in the top right corner of the Project Explorer Pane.
3. Click “Filters and Customization…”
4. In the “Pre-set filters” tab, uncheck “Java output folders” (thanks osoblanco for this tip)
5. In the “Content” tab, uncheck “Java Elements”

I didn’t see any difference between Flat or Hierarchical in the Project presentation, so I left it as the default.
I’m using Eclipse IDE for Java Developers version 2020-09. All of my projects use the default package, so I don’t really need to see “Java Elements”.
