I just deployed a new update (v1.1.1040) to add multiline Labels. I keep seeing people use Alert popups for player dialog and instructions, so hopefully this will provide a nicer option for those uses. The Labels have just been updated to add a multiline input box, and they will now render multiple lines.
Here is an example of some RPG style player dialog using the new Label update: http://flowlab.io/game/play/543877
In addition, there are a few minor bugfixes as well:
* UI behaviors were not loading properly for objects in UI layer - fixed
* When running the game from the behavior window the backgrounds would display incorrectly in some cases - fixed
* Animation behaviors will now select the first animation by default if none are selected manually
