Items in the right pane may be shown in one of four ways. Decide which way you want to see them, then click on that sub-menu. The four ways are:
Large icons
Items are shown left to right across the right pane with large icons, making them easier to see.
Small icons
Items are shown left to right across the right pane with small icons, allowing more to be displayed in the viewable area.
List
Items are listed top to bottom down the right pane using small icons.
Details
Items are listed top to bottom down the right pane using small icons. Detailed information about the item is listed beside it when available.
The last setting of this item, whether large or small icons, list, or details, is remembered when you exit ElkRP and is restored when ElkRP is started again later.
