By default, trame will open a new tab in the browser and bring it to focus. If this is undesired behavior, it can be prevented by using ```poetry run app --server```.
At times, it may be desirable to execute a tool or workflow without waiting on the result. The class Tool method run has an optional `wait` parameter.

The application should launch a tab in your web browser. The GUI will have a `FRACTAL` tab and a few sample tabs which were created by the template application. The run button on the `Fractal` tab can be used to launch the `Fractal` NDIP tool. The tool will take a few minutes to complete but when it does, the resulting `Fractal` image will be displayed.
