However, that stops working in the child tasks when you save the parent as a template then recreate the parent task in another workspace, from the template. (It's awesome that the child tasks get created automaticall though).
A possible answer then is to put a number at the start of each task name then [Order by: Task name]. Which is doable as task names are about the fastest things to edit in Feng Office (thank goodness).
Any other thoughts: I'd be interested to hear...
