Themes
A theme is a collection of colors, fonts, images, icons and sound 
settings that can change the appearance of Listers. By importing a 
theme that someone has created you can radically alter the appearance of 
Directory Opus. You can also create your own themes by saving your 
current Opus configuration as a .dlt file and share this with 
other people.
To access the themes system, select the Lister Themes 
command from the Settings menu.
 
 
The Lister Themes dialog displays a list of all themes you have installed. 
Initially your themes list will be empty - you can find themes to download on 
the Opus Resource Centre.
 
The File menu contains commands that let you manage your 
installed themes:
  - Import Theme: Select this command if you have downloaded 
  a new theme and you wish to import it to use in Directory Opus. 
  
- Export Theme: Select this command to export one of your 
  installed themes. This doesn't create a new theme - instead, the currently 
  selected theme in the theme list will be exported so you can copy it to 
  another machine or share with a friend. 
  
- Save New Theme: Use this command if you want to create a new theme. 
  
- Apply Theme Settings: This command will apply the 
  settings from the currently selected theme to your current Directory Opus 
  configuration. You can also click the Apply button at the 
  bottom of the dialog. As applying a theme will overwrite aspects of your 
  configuration, you may like to make a backup of your Preferences 
  first. 
  
- Delete Theme: Use this command to delete the currently 
  selected theme. 
 
When you select a theme from the list and apply it to your 
configuration, you can choose which aspects of the theme are applied - you don't 
have to apply all elements the theme provides. The options when applying a theme 
are:
  - Colors: This will apply the colors from the theme; these 
  are mainly the colors specified on the Colors and Fonts page in Preferences. 
  
- Fonts: This will apply the fonts specified in the theme; 
  these are the fonts configured on the Colors and Fonts page in Preferences. 
  
- Images: This applies any Lister background images 
  contained in the theme. A theme can apply background images to all elements of 
  the Lister (although only toolbars and menus that are set to use the 
  Standard Toolbar Image will be changed by this). See the Preferences 
  Images page for more 
  information on background images. 
  
- Sounds: If the theme specifies any sound effects these 
  will be applied. These are the sounds configured on the Miscellaneous / Sounds page of Preferences. 
  
- Toolbar Icons: If the theme provides any toolbar icon sets then these will 
  be applied.
