This page lets you configure the Windows Jump List - the menu that is displayed when you right-click on the Directory Opus icon on the taskbar, or that appears in the start menu when Directory Opus is pinned there.
This page is basically one big scrolling list of options that can be turned on or off:
Note that the size of the Jump List is not infinite, so even if items are turned on they may not actually be displayed in the Jump List - this is a limitation that Windows imposes on Jump List menus.
