Instead of replicating features from TortoiseGit the Delphi IDE should do things which external applications can't do. E.g. add blame to the editor gutter. For me the Git integration in XE7 doesn't feel much integrated and misses a lot features I have with Jcl-Versioncontrol + TortoiseGit + Beyond Compare.
