Themes are a way to customize the look and feel of Salesforce by changing the colors, images, and logos that appear on Lightning Experience pages. However, there are some limitations and considerations when using themes, such as: only one theme can be active at a time, and a theme applies to the entire org; themes apply only to Lightning Experience and do not affect Salesforce Classic or the Salesforce mobile app; up to 300 custom themes can be created, modified, or cloned from the built-in themes; Chatter external users see the built-in Lightning theme only and cannot see custom themes.

Default language and currency locale are two options that an administrator should configure in the company settings to support a global team of Salesforce users. Default language determines the language that is used for labels, buttons, tabs, help text, and messages in Salesforce for all users unless they override it in their personal settings. Currency locale determines the format of currency fields and numbers in Salesforce for all users unless they override it in their personal settings or enable multiple currencies.

Screen flow allows you to create a form that collects user input and performs actions based on that input. You can use screen components to display questions and instructions, and use flow logic to update records or send notifications.

One thing that an administrator should be aware of before changing an auto-number field to text field is that this change is prevented by Salesforce; it cannot be done because it would cause data loss and inconsistency. Auto-number fields are fields that automatically assign unique numeric values to each record; they cannot be changed to text fields because text fields do not have this functionality and may allow duplicate or invalid values. Existing field values remaining unchanged, being converted, or being deleted are not things that would happen before changing an auto-number field to text field because this change cannot happen at all.

Grant access using Hierarchies is a setting that can be used to configure the custom object to meet this requirement. Grant access using Hierarchies determines whether access to records of the custom object is granted through the role hierarchy. If this setting is unchecked, managers are unable to see the feedback records from their staff, unless they are given access by other means, such as sharing rules or manual sharing.
