Tool for detecting and removing duplicates? [Available in 8.10.18]

Please add a vote for me. In the migration from 1password 7 to v8 I've ended up with thousands of duplicates. I've been using 1password since February of 2008 and have never run into this kind of frustration.

I spent a half hour manually command-clicking and deleting duplicates and barely made a dent in it. The duplicates crowd my view of passwords whenever I try to use 1password to login to a site.

The duplicates are all exact dupes, with all entries and content and the same modification and creation timestamps. There wouldn't be a need for a tool that does fancy comparisons between records -- just quickly scan through all of them and generate a hash for each, then delete one of each matching pair. Maybe I'll see if I can figure out a way to automate this with 1password-cli.
