New 2019.1 Feature
The documentation states:
Open the current configuration on startup: When this option is selected the Workflow Configuration tool automatically starts with the configuration that was last sent to the server. Otherwise no configuration will be opened at the start.
Unfortunately, when unchecked it will not allow you to double click on any .OL-workflow file to open it. You are forced to navigate to a file to open it.
The feature really would be much better if it allowed the opening of a .OL-workflow file by double clicking on it regardless of the check box setting.
