At present the matcher columns for a transaction are only labelled Deposit or Withdrawal and these headings do not change to Debit or Credit when formal accounting labels are used. This can make importing confusing for those of us who routinely use the formal accounting labels. Deposit/Withdrawal do not make obvious sense when applied to a Liability account for example.
I have added a possible fix for this in PR442, need to wait to see if accepted.
I have dropped this from the PR as it needs more thought.
