Using you Calendar as a ToDo list video

i watched this video today. https://www.youtube.com/watch?v=3eid1GEi6kc

It was quite interesting. The system would never work for me because i want (need) many of the features Quire provides.

But i did agree with his description of the need for a Start Date that actually functioned like a real Start Date and i was surprised when he said there are not many Task management systems that manage the Start Date well. I have raised that issue in #1307
