These three features allow fields to be available when viewing a record in Salesforce.
A highlights panel displays key fields at the top of a record page in Lightning Experience. It can be
customized to show the most important information for each object.
A compact layout determines which fields appear in the highlights panel, the list view hover, and the
Salesforce app. It can be assigned to different record types and profiles.
A list view displays a set of records that meet specified filter criteria. It can be sorted and filtered by
different fields, and users can select which fields to display in the list view.

A deal closer is someone who is responsible for closing sales deals with prospects and customers.
They need to update existing prospect and customer records to keep track of their interactions and
status. They also need to log activities such as calls, emails, and notes to document their
communication and follow-ups. They also need to review and work through their list of leads or
opportunities to prioritize their tasks and identify the best prospects to focus on. These activities are
essential for a deal closer to manage their pipeline and achieve their sales goals. Creating cases from
issues and customizing and administering Salesforce are not activities that a deal closer would do
each day. These are more likely to be done by a customer service agent or a Salesforce administrator,
respectively.
