There may be times when you want to have labels be multiple lines. Multi-line labels allow them to fit in tighter positions on the map. Currently, in MAPublisher LabelPro there's a rule to allow stacking up to 2, 3 or even 4 lines. However, this rule only "allows" stacking and doesn't "force" stacking. It is only meant to fit labels when there isn't enough space for a single line.
