Similar to the bullet (.uno:DefaultBullet) and numbering (.uno:DefaultNumbering) list split buttons found in the formatting toolbar, we need a similar one for outline lists, to include entries found in the Bullets and Numbering dialog's Outline tab.
No problem.
Thanks Maxim. You can add it as a hidden entry in the formatting toolbar after numbering, for those who want to enable it.
