I frankly don't understand the Synchronize view in a Git context since
it doesn't deal with commit (change sets). To me "synchronize" in Git
would be something like an interactive rebase/cherry-pick in a pretty
GUI:y dress.

We once (version 0.3.1) had a structured compare in the history view
that we should resurrect, or rather re-implement. It was very fast,
typically much less than one second to compare two revisions and a new
implementation should be faster.
