To better plan my day, I have 8 hours in a day, I would like to see the sum of the estimated hours when I mark my tasks for today so that I know when my day is full.
The quickest way to do this would be to multi-select the tasks in the Today section in My Tasks. this will give you an instant total:
To multi-select, you just click on the first task’s title, hold down shift and click the last task’s title.
Hope that helps!
