Something that bugs me with almost every source control GUI is that there is usually no way to spawn a three way diff after a merge has been done. They might support three way merge on conflict but bang, once you save you can not get that view back. They also often don't understand that no branch was the master branch so if you diff the merged revision (diffing a single revision doesn't make sense yes but guis usually present it this way and diff it with the last revision) then you get all changes that has happened on master since the branch was created, wtf?? To see what only the branch contributed you have to manually select two revisions, diff them and then select the other revision and diff.
