There are 2 ways to see summarized report for your projects, clients or team members.
1. Activity report
On the Activity report you get a GROUP BY selector. When you need to view how your (team's) time is distributed between projects, select 'GROUP BY > Project' and you'll get a summarized report by projects. To see only the totals, choose to 'VIEW > Groups'.
You will find your summarized reports in the Dashboard view as well.
