The home screen shows all your outlines, and their current sync status (a pencil on the outline icon indicates that the outline has been modified since the last sync). From here, you can create new outlines using the '+' button.

You can sync your outlines to Outliner Online, the free online companion to CarbonFin Outliner. Syncing protects you from data loss, and allows you to import, export, and view your outlines from any web browser.

Pressing the Edit button on the home screen allows you to easily rearrange or delete your outlines.

Outliner is great for task lists, such as a shopping list. Just tap the checkbox to mark each one complete, or tap the pie chart next to a parent task to mark or clear all subtasks.

Outliner is especially good at managing simple projects. Organize your project into hierarchies of tasks and subtasks, and see at a glance how each part of a project is progressing.

Not everything you store in Outliner are tasks. For flexibility, each outline has a setting to allow you to show or hide the checkboxes and show or hide the notes preview, giving you more room for text and notes. New in v1.4, you now have the option to show numbering for items.

New in v1.4, you can easily collapse/expand all items or collapse all completed items. You can also now duplicate an item or entire tree of items within an outline.

Each item tracks the time it was created and completed. If an item has a note, a single line of the note will appear in the main outline view.

You can easily export any outline by emailing it as plain text, or industry standard OPML. Using OPML allows you to export your outlines for desktop editing in your favorite outliner.
