It would be helpful if the duration coulmn could have different unit settings. i.e. the default and only unit right now is the number of days. But for certain projects it would be more helpful for the duration column to auto-calculate to being in hours, or in other cases weeks. I know you can manually adjust the duration witht he unit that you prefer for that column, and further refine this through the RM application. but still having the option to adjust the default unit would be nice for estimation purposes.
