Sorting PRs by merge date #2287

From time to time, I do a quick summary to the team of what went in production since last time.

When I'm viewing my merged PRs, I would like to see them sorted by merge date. That way, I can quickly see what are the new features that were merged since last time I did the update. At the moment, it's possible to sort by time of last update, but it's not always the same as the time the feature was merged.
