Preferences Categories

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!

Display: Options relating to the appearance of Opus (colors, fonts, etc.). The page to change the user interface language is in this category.
Favorites and Recent: Options relating to favorite folders or folders that are otherwise important.
File Displays: Options that control the behavior of the area of the Lister that displays files.
File Display Modes: Options specific to certain display modes (Thumbnails, Details, etc.).
File Operations: Options that control file operations (copying, deleting, etc.).
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.
Internet: Email, proxy, update checking, other settings relating to how Opus uses the Internet.
Launching Opus: How Opus is launched, what it does when it's launched, and whether to replace Explorer or not.
Layouts and Styles: Options to control saved Lister Layouts (arrangements of one or more pre-defined Listers) and Styles (pre-defined configuration of an existing Lister).
Miscellaneous: These are the options that wouldn't fit anywhere else.
Toolbars: Options relating to toolbars, and toolbar icons.
Viewer: Options relevant to viewing images either in the Lister or in the standalone image viewer.
Zip & Other Archives: Options that relate to various archive formats that Opus supports.

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 - Cursor Up/Down to move up and down and Cursor Right/Left to expand or collapse a category. You can also press * to expand all categories at once, or - twice to collapse all categories.
