Add history of selected files.

[lolgear]

It would be nice to git log selected files to show history.
SourceTree has this action: cmd + alt + L on selected file in selected commit.
This feature can be done as an action on detail commit view. ( hit Space in Map View )

But it also possible to add additional view at right in Map View which show commit message and files. From this view you can select file and open its history.

Am I right that if I want to add this feature in GIQuickViewController ( file contextual menu ), I need to add delegate ( Document ) to QuickViewController, which will ( in terms of MVI ) handle intent quickViewController:wantsShowHistoryForSelectedFiles:?
