When performing forensic analysis regarding how or why something started working differently, it would be a great timesaver to be able to select a component and then be able to select the data comparisons for just that component. For example, select an apex class and then pick date dates so the system can display what changed. I would expect that this would be quicker than going into Monitoring Histories and picking each date and waiting for it to build the entire comparison of everything that changed and then having to find the component of interest.

A follow on to this would be to be able to select a limited list of components (maybe multiple apex classes, or apex classes and related triggers, etc.). But I won't be greedy...
