Version 1.1 of Editus introduces new features. From the Editus Settings page, you can configure Editus to add Ordered/Unordered (OL/UL) buttons to the toolbar.

To use these buttons, first type texts with one or more paragraphs.
Then select the text and hit either UL or OL button. The paragraphs will be converted to lists.

You can try this new feature at the demo page.
