The various Preferences pages have been categorized in an attempt to group conceptually-related topics. Another advantage of dividing the pages into categories is that individual categories can be collapsed to hide their contents, which is very useful with so many different pages of options!

  • Colors And Fonts: Options relating to the appearance of Opus (colors, fonts, etc.) including dark mode and themes.
  • File Displays: Options that control the behavior of the area of the Lister that displays files.
  • File Display Columns: Options relating to information columns in details mode (including creating your own custom columns).
  • File Display Modes: Options specific to certain display modes (Thumbnails, Details, etc.).
  • File Operations: Options that control file operations (copying, deleting, etc.).
  • Filtering And Sorting: Controls relating to filtering and sorting file lists.
  • Folders: Options that relate to the display of specific folders (a certain folder can always appear sorted by size, that sort of thing).
  • Folder Tabs: Controls relevant to the behavior of Folder Tabs.
  • Folder Tree: Options that relate to the Folder Tree.
  • Frequently Used Paths: Options relating to favorite folders or folders that are otherwise important.
  • Internet: Email, proxy, update checking, other settings relating to how Opus uses the Internet.
  • Labels: Labels and status icons that you can assign to your files.
  • Launching Opus: How Opus is launched, what it does when it's launched, and whether to replace Explorer or not.

When the input focus is on the category / page list, you can navigate it using the keyboard in the same way as you can with a tree control:

  • / to move up and down
  • / to collapse or expand a category
  • * to expand all categories at once
  • - twice to collapse all categories
