What to do when a todo is partially completed

[Glyphack]

sometimes a todo is partially completed, we can add a feature to make it easier to deal with this. Right now I keep the task in my todo and snooze it for tomorrow, but the todo title stays the same and I remember how far I completed it.

We can to make it easier we can add another form of completed that the person can mark todo as partially complete and it will disappear until other tasks are finished then we show that todo again if they decide there is time to finish it they can complete it otherwise they can split the task into two parts and move the other part to tomorrow.
