Also, if I'm allowed to be particularly anal, there's a small line / bar on the left side of that box list that, if it were in Excel, would suggest that there's a collapsed / shrunk column. It in no way affects functionality as far as I can tell but I figured you may want to know.
That is in fact a collapsed column that I only found out about recently.
If you go to the Filter List Box below the table in the Transaction tab, and select "Custom Filter", you will get a column that allows you to hide or display ledger entries for selected rows.
