Yes, it does work - and it's really fine that way on reflection. After a few hours playing around with it, I'm actually really enjoying the 'manual' aspect. It's quick and easy to add elements to the day and the process of doing that also forces me to reflect on priorities and what is really necessary to get done.
There's always a risk that developing these things ends up somehow losing the essence of the thing, and that would be a real shame.
Such a great idea and a nice implementation Tom which deserves a wider audience. Best of luck.
