In the last few updates my MacBook Pro fans have been going crazy if Storyboarder is open, even if it has no opened scene, and is in the background. The example screenshot isn't the worst it's been. This is with v1.4.1, but the problem was there previously.
Same problem with build 1.9.1 on Macbook Pro running macOS Mojave. After a short while the fan is running at full speed and the Storyboard Helpers are eating up CPU.
