Soc once said it best in Discord explaining they solve problems by approaching them like they're programming problems. To elaborate upon that, you basically need to identify what you are trying to do or needing to do, and then figure out how to solve that very specific problem. Isboxer is a very dynamic software that allows for an immense amount of customization and features. There are quite literally dozens of ways to do a task. Managing a healer is a good example of this. Talking to someone who is an expert at isboxer would take a lot of time to get something setup for how that person does something, but a lot of people approach healing slightly differently based on what they're comfortable with. There certainly is no "right" way to do something.

The best way to learn this software and get better with it is to start at the beginning with the quick setup wizards and as you are doing things, identifying where your setup can be improved upon. Your setup will be an evolution and will eventually get where it needs to be.

In short while it seems like having an expert help you, I think it would be mostly a waste of time for all involved. You'll be better off working through the challenges of multiboxing yourself, and asking questions along the way when you get to very specific things. I would recommend being patient, I've found actually learning the software to be fulfilling in itself.
