EnSight uses several sets of icons to group functionality. The Feature Icon Bar can be customized in terms of which features are available and what order they will be presented. All of the icon bars can be moved and docked or undocked. In addition, all of the list panels (part, variable, viewports, annotations, query/plots, and frames) can customize the columns of data displayed in the panel.

The icons can have text subtitles under the icon. Many users find it useful to turn this text on while they learn the system and turn it back off once mastered.
