Once Swimlanes have been added to plans they are very easily updated.

To Edit a Swimlane click into the Swimlane Title. This will launch the Edit Swimlane Modal window.

A Swimlane can be edited until the point that the Plan becomes active.

When editing the Swimlane No, and a new order number is given the Swimlanes which sit in that position or under will be moved down the plan to accommodate the moved lane.
