There are a few ways to change how you view the results in a dataset. At any point, you can slide the separator that appears once you hover over the black divider to one side of the screen to maximize either the Topic Explorer or Table/List of Results. In addition, you can collapse the Refine Filters Panel by clicking on the purple arrow at the top of the panel.
To expand your results and view more rows of records in a larger window (full screen), click the Maximize button in the top right corner above the Results table. To minimize and return to the normal table view, click the Minimize button in the top right corner of the window.
