Hi James.

I'm glad to have you here on this thread. I can share with you on how to save the column width on your reports.

To save the column's width of your report, you can memorize it by selecting the Save customization tab. Here's how:

1. Open the report you need, then adjust the fields from there.
2. Make the necessary filters and the rest of the customization (columns, transactions, dates, and others).
3. Tap on the Save customization tab.
4. Enter the report's name and the other details.
5. Click Save.

Then, here's how to open the report in the future:

1. Click on Reports at the left pane, then tap on Custom reports.
2. Look for the report from the list, then open it.
3. The report's settings and columns' width are saved.

Please let me know how else I can help you with your reports. I'm more than happy to help. Keep safe!
