Thanks for sharing your feedback here in the QuickBooks Community, @gerryran.

I understand how increasing the character fields in QuickBooks Desktop would be helpful for you. Since this option isn't available as of the moment, I'll make sure to take note of your request and will update you once we receive product enhancement update about the availability of this feature.

In the meantime, I'd suggest visiting our QuickBooks Desktop New Features regularly. This way you'll be updated with the latest news and updates including product improvements. Just simply go to the Help menu bar, select New Features then click New Feature Tour. 

For additional reference, you may want to check this article to learn more about the character limitations for fields in QuickBooks. 

Please know that you're always welcome to post if you have any other concerns about your QuickBooks service. I'll be around to help you out. Have a good one.
