I can see how the benefit of being able to export the product list including a column for the product categories would aid you in running the business with QuickBooks Online (QBO), @1938CDB. That's why I'm here to share a few details about this.

For the time being, it isn't possible to export the product list that includes a column for the product categories. We take customer suggestions as opportunities to improve the various features within our products. Therefore, I would encourage you to send suggestions or product recommendations.

Your valuable feedback will be forwarded and reviewed by our Product Development team to help improve your experience while using the program. Here's how:

1. Go to the Gear icon.
2. Select Feedback.
3. Type in your recommendation in the Share your feedback field.
4. Click Next.
5. Follow the on-screen instructions to complete the process. 

I've attached screenshots below that show the first four steps.

Also, to further guide you in managing the growth of your business and transactions using QBO, I'd recommend checking out this article: QuickBooks Help Articles.

On top of that, I'd also recommend visiting this page to keep you updated with the latest software improvements and enhancements with QBO: Customer Feedback for QuickBooks Online.
