Great question. I tried to develop such things, but I struggled to manage my time (what a pity). I thought about a system accessible through different media (mobile, laptop, desktop, browser), with labels (work/family/self), location (home/work/commute), best time to do (morning/afternoon/night) and dependencies. Once in a while, the system remind me (notification) to do one selected thing. Either I accept (and the system ask me after the duration of it's completed) or I deny and the system ask me why (fill dependency, location etc.) Before presenting me something else.

The complexity is to synchronize on all platforms, to have a nice and easy GUI, and manage the dependency (priority?)

Good luck with that and stay in touch if you come with something.

Thanks for the detailed answer. Would you mind talking a little bit more about the dependencies? What do you mean by a dependency? Is that like another task that needs to be finished before the current one? What is the relation with priority?

[Isammoc]

Yep. Dependency: a task that needs to be finished before the current one. A dependent task is always lower priority than its required task.

Dependency and priority are both levers to be able to choose the right task to do (perhaps adding an importance level?)

A task that depends on unfinished ones cannot be proposed by the system. Between two possible tasks, the priority one will be presented first (or perhaps a computation with priority, importance and duration?)
