I like the connection to Sales Navigator to support social selling efforts as well as the Outreach Everywhere plugin. Both of these facilitate easy communication with prospects. The Sales Navigator connection makes it easy to identify the right contact in SN, save them to a list in SN for interaction with at later dates. The Outreach Everywhere Chrome plugin makes it easy to see what's happening with a contact in SF. Snippets are also really effective in reducing the time sellers spend hunting for content. They can easily respond to a customer's request with links to content the marketing organization builds for them.
