I think there are a couple of very small glitches. Working backwards, I can only see the first 20 entries. Once I work down so there are 20 outstanding early merge requests, I cannot get any more. It defaults to the most recent.
Also, if you click Merge when a Merge is already outstanding, the entry acquires a new activity date of today, making it very difficult to see which are the earliest outstanding Merge requests.
But this is a great tool. Love it!
