Seriously, I think this is everything I've been hoping for. You solved all my problems with time-blocking with this very elegant solution.
I've been using it for less than a day and I already feel that I'll be using it all the time. I hope you develop it further, maybe into a standalone app with a facility to import from apple calendar and apple reminders. Having said that, I also quite look how you need to add things manually. makes me think about what I'm planning on doing a little more and get my day straight in my mind.
Thank you so much for creating something so wonderful.
