The two primary types of contacts in Lexicata are likely to be your Leads and Clients. We created specific pages for each of those, so you can quickly navigate to them from the left sidebar by clicking either the "Leads" or "Clients" links.
You can view the rest of your contacts (Did Not Hire, Unassigned, and custom contact statuses) from the View All page.
On each of these screens, the list of contacts will be displayed in a table format. You can sort any column by clicking the column heading at the top of the table. The little arrow indicates which column is currently being sorted, and whether it's in descending or ascending order.
