Package Management

Quickly install many assets at once
Track what versions of assets you have installed so you know when you need to upgrade
Easily manage an offline repo of assets. Add a directory containing unity packages and all of the packages under that directory will show up in the package manager. This makes dealing with assets downloaded from third parties like the Synty Store or CG trader easier.
Bookmark github based package manager packages for easy import
Save import time, search for prefabs in assets you haven't imported yet
