The feature request is quite old, but answering psantosl, I still think I would like to see just the changes introduced when merging the featured branch with the head of the target branch.
If the diff is displaying already all the history/merge/etc, I suggest we get a button to 'hide' all those changes, because when in the original branch there have been a lot of changes, you get all those changes within the specific branch changes.
