I used to use OmniOutliner to do quick time estimates but as it is mac only I need a windows replacement for work.
Here's my use case: I want to be able to break down my projects into sub-tasks with work hour estimates that can be rolled up to each parent in the hierarchy. (the bold italic font indicates a calculated field).
total ***42h***
task 1 ***23h***
subtask 1.1 3h
subtask 1.2 20h
task 2 ***19h***
subtask 2.1 16h
subtask 2.2 ***3h***
subtask 2.2.1 3h
Any suggestions?
