You can create and save LeadViews the same way you can create Job and Calendar Views, to customize how you view information at a glance. For example, you can filter your Lead Views by Salesperson for a quick View of which Leads are assigned to which Salesperson.
From the left side navigation, click on Leads.
Click on the Options button from the top menu.
Click on the + icon to the right of Filters to add a Filter.
Select Filter Type: Lead FIeld. Select Lead Field: Lead Salesperson. Select which Salesperson(s) to view or exclude.
