Prior to the upgrade, we were able to correlate data historically, on a build by build basis, showing deltas and trends in code submissions. Especially useful was the ability to customize views using the "TimeMachine".
When showing this data to our DEVs - they LOVED the trend information presented, so that they could see the direct impact to a build they made for each submission.
We WANT to upgrade, because we do like the new "filters" for projects main page (All/Favorites) - and we enjoy staying current...
... but the loss of dashboards is a HUGE negative impact for us.
We'd love to see dashboards "come back" / be re-implemented.
Feedback is a gift... :)
