CSBox:I would be interested in this feature as well. We always project hours for each task and it would be great to see the actual billable hours against the total hours. Additionally, it would be nice to have a "client" facing progress bar where they don't have access to the timesheets but just see the progression bar. Finally it would be nice to assign hours to a task. I have played with a trial of Harvest and it would be nice to see some of the feature set migrate into activeCollab.
No reporting or quick budget/actual compare features at the mo but they will come. Any suggestions of how you guys might find this useful would be greatly appreciated :)
