Animation tag matching
When you apply a transition to a screen or a behavior to a group, tags will be automatically applied where the tag name matches the layer name. This can be convenient if your layers are named in the right way.
For example, if you have a transition or behavior with a tag named Baz, and you apply it to a screen or group with a layer named Baz, the tag Baz will automatically be matched with the layer Baz. If a match is not found, the tag will be unassigned and you can assign it manually.
Behaviors have a special case where any behavior with a single layer and a single tag will have the layer automatically matched with that tag, regardless of a name match.
