Hi Colin, this was super interesting. I build one called Twos (https://www.TwosApp.com). Not necessarily a strict task manager, but is more all-in-one like Brite, but simpler, and designed around *things*. *Things* you need to do, *thing* you want to remember, *things* you want to be reminded of. We do all but probably requirement #7, although #1-3 would require you to create lists for the vague blocks you want. Would be interested to hear what you think
