Thanks so much everyone for helping. Especially Brian for that clarification and the missing piece. I had not come across the Edit->Sort menu before and that was indeed the missing step I was looking for. I had assumed you should be able to just click on the Due label at the top of the Due column to sort by that – but that doesn't work.
This will make my life a lot easier for sure. Thanks again for taking the time.
