The feature request
When you compare two branches in order to prepare a merge it could be relevant to explicitly show the liste of conflicting files

Proposed solution
On my side I have developped a bash extension called nogit that can preview (in a ugly way) the merge by combining behind, ahead and conflicting files (taking into account auto-mergeable conflicts)

A pretty version of that could be integrated in a tab to help user to manage the merge.
I use nogit for several years and this feature is really decisive for complex merge.
