All the projects I've done professionally were estimated in days and it's still true for my current tasks.
A good improvement to Redmine would be to be able to choose the unit of time.
In the forum thread message#10111, http://www.redmine.org/boards/2/topics/10111, someone proposed to add a unit of time to the value which could be a solution.
But this could imply that every user should set what hours mean a day and how many days are in a week.
Anyone interested ?
