How to I change the workbench theme for a different appearance?
Altair EmployeeIt is possible to change the background theme using Window->Preferences->General->Appearance where you should find a pulldown list of supported themes including 'Dark'. The workbench is essentially a plugin to the Eclipse IDE framework meaning sites such as http://guari.github.io/eclipse-ui-theme/ may provide some other alternatives but searching for 'themes in Eclipse' in a search engine might reveal more.
However changing a theme can affect the way the SAS language program appears in the editor tab as the default syntax highlighting colours may not blend well with a dark background. You would then have to 'fine tune' the colors using Windows->Preferences->Altair->Syntax Coloring and choose more appealing colors for each SAS language structure by first highlighting the item in the list and then select the 'Color' box to change it.
The theme may not change *all* tabs in the workbench as some like the Log,Listing/HTML, dataset viewer etc.. are special output tabs from executing programs and will probably not have this customization. However we hope there is enough here to make more agreeable customizations.
