Sum the time in a project/parent task


I don’t request many features in OF, but one that would really be helpful to me is a sum feature for projects, and parent tasks. That way when I begin a project (e.g. Half Yearly reporting), I could see that it’s going to take 12 hours to complete with all the sub/child tasks embedded underneath, and that a sub project (Year 7) will also show that it would take 3 of those hours. Then as a child task is completed, for example the comments fields in the Year 7 reports, the totals would reduce automatically, letting me know I only have 2 hours left for the Year 7 reports and 5 hours left on the whole reporting project. (etc)
