I would like it very much if the Estimated Time field for a project automatically summed the estimated times of its actions. It would also be nice if that was the default value, but the user could override it by manually entering a time (sometimes I use the project time estimate as an elapsed value instead of an "effort" value).

I did a search on this and found an applescript in the Extras forum that sort of works this way, but only on selected items - I'd like it to work automatically for all projects. If this has already been requested (or is already available and I just haven't stumbled upon it), I apologize.

I would also love to hear any workarounds that people are currently using.

(NOTE: Also submitted via email, but I wanted to know if others would find this useful)
