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

spinoza:

Just fyi, when I imported my stand-alone vaults I wound up with several thousand duplicates, and no way to remove them except one-by-one.

Make sure you take a look at the list of tags in the 1Password app: every round of import you performed should have been assigned a specific tag with the import date, so you can select all duplicates at once.
