Sum of billable hours in the timesheet

In the timesheet it would have been nice with an option to see the sum of only billable hours. In my company we have a requirement of upkeeping at least n billable hours for each week. But we have a lot of activities that are not billable. The totals line in the timesheet sums the amount of all activities, and this clutters the view if one only want to see the sum of billable hours.

I know that we can use the reports view, but that’s too far away. A dream scenario would be if we could customize more of how the timesheet would behave.

Keep up the great work! Cheers!
