Need more columns on the Accounting Batch screen

[SarahG (FountainTribe)]

When a user is using the "Accounting Batch" screen to view transactions in a batch, and/or add transactions to an open batch, there are not enough columns shown for the user to understand what they are seeing (and most importantly, add the desired records to a batch)

What PHP file should I be editing in order to add more columns to the screen at: http://mygroup.org/civicrm/batchtransaction?reset=1&bid=12  ( in this case I am editing accounting batch id = 12, but could be any open batch)

Example Scenario where there are issues:
The user creates a contribution  for the total amount 50.00 for financial type "Gala Dinner" which has a payment processor fee of 2.00. (payment instrument is Credit Card).     This results in 2 bookkeeping records: record "A" record showing 50.00 with credit/debit involving the asset account of credit card, and the "Income" account of "Gala Dinner". record "B" showing 2.00 with credit/debit involving the asset account of "Banking fees", etc.

If the user reviews these records on the "Bookkeeping Transaction Report" and enables the columns for debits and credit, then everything makes sense. ( ie its clear to the user the differences between the 2 records. )  However, if the user attempts to use the screen at: http://mygroup.org/civicrm/batchtransaction?reset=1&bid=12   then the 2 records appear identical because the screen lists the amount as "50.00" for both, same financial type for both, etc. So the user has no way to determine which record they should add to their batch.

(This scenario occurs anytime there are payment processor fees on the contribution record, contribution could be from a self-service page, or back-office, etc)
