Using the built-in view settings

OmniFocus includes several preset view configurations, similar to perspectives (except that you can’t edit them). These view settings appear in the Perspectives menu and they are also available on the default toolbar. (If you customized your toolbar prior to OmniFocus version 1.5, you may need to choose Customize Toolbar from the View menu again to add them to your toolbar.)
Inbox — This takes you directly to your inbox, where you can enter new items.
Projects — The most basic view of planning mode, showing your remaining actions organized by project.
Contexts — The most basic view of context mode, showing your available actions organized by context.
Due — Remaining actions that are either due soon or overdue, grouped by due date.
Flagged — Actions you have marked with a flag, organized by context.
Review — Your remaining projects, organized by their next review date.
There are also a couple of very inclusive settings that are available in the Perspectives menu, but not as toolbar items. These are handy if you think something you created has gone missing:
Completed Items — All of the items you’ve already finished.
All Items — Everything in your database, except for things you have archived. This may take a while to load.
