@lubos Could the “Autofill — Line description” field be displayed as a column in the chart of accounts? There are a number of request topics on this issue, and some of them suggest adding a custom field to the chart of accounts for account description/purpose. But I believe this idea will be best.

Inbuilt accounts do not have the “Autofill - Line description” field. However, this is not a problem because the reason for their existence is clear and easily understood.
