The Package Manager window displays the list of feature sets, packages, or Asset Store packages according to the criteria that you select by filtering, including, or searching:
(A) Feature sets appear at the top of the list view, indicated with the feature set icon (). Toggle the expander icon to show or hide the list of feature sets. When you select a feature set from the list, details about it appear on the right, including a brief description, a list of included packages, and a link to the QuickStart guide for that feature set.
(B) Registry groups organize the list of packages installed in your project (or available for installation when you are in the My Registries context). Select the expander on the left to show or hide the list of packages for each registry.
(C) Select these expander icons to show and hide the list of versions installed or available.
(D) The package version displays the version of the package that’s installed. If the package is not yet installed, the version that appears is the recommended version. Special icons often appear beside the version number indicating its state:
