Hi.

I would be great if in task options you add option: estimated time.

Why it need:

For example.
I have 30 minutes free.
I finish all my tasks for today.

I open, for example, "Next". And check in the list of task how much time need to finish each task.

I will be easier to choose what to do for 30 minutes free and no need to read each task and think how much time need to do it.
