We have users that would like to be able to resize nodes such that they span multiple lanes.

These nodes should still be "registered" as part of the swimlane.

Typical use case:

1) User drops a new node in a lane

2) User then resizes the node such that it now spans multiple lanes

See the attached video showing how this works in Visio.

Ideally, this feature would be enabled through a swimlane property/constraint, although I'll leave the actual implementation up to you.

Thanks for considering this feature request.
