The Project view displays the list of packages currently installed in your Project from all sources. This means that immutable packages that you installed from a package registry are visible, as well as mutable packages (such as embedded and local packages).
You can inspect the contents of any package that appears in the Project view. You can also inspect the package manifest through a dedicated Inspector.
To inspect a package manifest, click on it in the Project view.
For embedded or local packages, you can change the package contents and edit the package manifest.
