I have a little suggestion regarding the “Suggested Reason Statements” under Reasons for Merge.
It seems to me that quite often users will just click one of these reasons statements as their reason, without a clear reason for the merge. I’m wondering if it may be too convenient for some and it doesn't give other users much comfort that their reason is valid.
My vote would be to have all of us come up with our own written reason statements for any merge.
The suggested reasons are relatively new. In the preceding merge process, you just got an empty box. Most people left it that way.
One advantage of the canned reasons is that they all include both IDs. This makes it much easier to figure out what happened, especially when you're looking at a family member's change log, where the merge is expressed as a sequence of additions and deletions that otherwise make no sense.
