It's far less convenient; I would look into fixing whatever the issue might be but I don't know enough about how it works.
The application takes some getting used to and is a bit more hands-on. If anyone runs into issues with it, don't hesitate to message me about it. However, please make sure to thoroughly read the help files that come with it. I'm open to questions, suggestions, and issues with the program, but nothing is worse than questions that are clearly answered in the documentation.
