For example, I've added "Other Expenses" for couple of one-time purchases of new car and one time house repair expense. When these are in the table along with other "Other Expenses", hard to distinguish which is which for including/excluding in a Run.
If there was new free form text field (could be added below "Taxable Percent" field) to type in things like "car", "redo Bath", etc, then put the free form text in the table. It would be ok to make the table scrollable horizontally and the free form 'hidden' on the right - the free form text is for reference and would be used only occasionally to confirm what "Other Expenses" that have been added to the table.

Thanks,
Mike M.
