With LeadExec, you can bring any fields removed back into the header bar by clicking the Column Chooser option added to the List screen. You have complete control over what columns display in the List view.
To move or edit your columns:
Click Choose Columns
The column editor will bring up a window on the bottom right of your search leads screen that contains all fields previously displayed on the search leads report.
Click the field you wish to bring back into the report and place it where you want it displayed.
The column editor will allow you to move and hide fields you don't use without having to click Restore Defaults if you accidentally remove a column field.
