Why are boxes 24, 25, 26 and boxes 10, 11, 12 summed on a T3, and 49, 50, 51 and 23, 32, and 39 on a T5 in the summary window in Forms view? 

The sum of the Actual amount of dividend plus the Taxable amount of dividend plus the Dividend tax credit is a nonsensical total.  This makes it hard to check if totals have been entered correctly, totals split properly between spouses etc.  Looks like there is easily room to show these as separate line items instead of summed.
