I oftentimes have tasks that have smaller mini - tasks associated with the main task. It would be neat if the task could be kept under one task. I realize there is an activity series, but sometimes it would be better if there was a tree-like/accordian like structure for multiple mini tasks.
For example, Send Fax to X company
a) - make sure the proposal has the right figure of $10,000
b) - make sure Joe Smith is faxed on the proposal also.
This make sound like a "detail", but to me it's a task/subtask
A detail would be; Construction cost of the project is $6000. See Ron about the risk of cost overruns.
