Expose billable hours in task list view
In the task view, it would be extremely helpful to see the total number of hours already logged for each task (I.e. as a separate column). While this info is available it's another click away and then you can only see the total one task at a time. Having this info visible in the list view would allow you to get a quick picture of where you are from a budget/hourly standpoint and see which tasks are at risk.
