When End Users are familiar and comfortable with their List Pane column headings introduce them to icon only display. As icons use less column space, more columns will fit on the screen for record identification.
Our first screen shot, below, displays the full details for the status of a record under the Edit Status column (Checked In, Checked Out), including displaying the column title.
To display only icons in a column, Right Click on the Column Heading > Display > Icon. In our example Edit Status is changed to an icon only in the columns.
