Personally, my mental to-do model consists to a pretty large part of recurring tasks with more or less vague &quot;deadlines.&quot;<p>For example, at home, taking out trash, watering plants, stocking up on groceries, paying the rent, etc.<p>However, almost all to-do systems seem to be aimed at scheduling one-off tasks.<p>So I would like the to-do system to more accurately model my real to-do model, which would probably mean having a special item type for these circular, Sisyphean tasks.
