Configuration - Word Wrap Long Labels

The Planner Appearance section of the toolpart has Word Wrap Long Labels option.

Word wrap long lables option

By default, Planner will truncate labels when the item they appear on does not have sufficient space to show the full text. The full text can be viewed as a tooltip by hovering over the item.

Example with word wrap off

Ticking the "Word Wrap Long Labels" check-box will cause Planner to show the full text of each label, text wrapping onto multiple lines if necessary. This feature may be useful when you need to print out a Planner view and the tooltip is not available.
