P: A merge approved from both sides but unmerged is difficult to spot.
S: A way to easily identify such cases would be helpful.
P: A merge involving an orphan is difficult to spot.
S: A mention of the orphan status in the list of merges would be helpful.
P: A manager proposing a merge has to go back to approve the merge.
S: Automatic approval should be implemented. If retroactive, even better.
Altogether, a new ordering possibility of the merges based on the easiness to finish the merge(such as the ones mentioned above) would be a nice feature for 2014.
