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

@"Chris Messina"

That's a real bummer. I'm sorry. 😞 There are a number of different ways duplicates (or similar items) can occur, and as a result it is likely that more than one solution will be required.

1. For imports (v7), as Ana mentioned, a tag is created for the imported items. This makes it easy to identify which items were imported when, and if an import is accidentally performed twice it'd be possible to simply delete all of the items with one tag or the other. v8 does not yet support importing, but hopefully we'll do the same or similar there.
2. For migrations from standalone, we now write out a hidden "migration receipt," which tracks what has been migrated, in an attempt to prevent duplicate migrations. This does break down if that receipt, stored in each standalone vault, doesn't get synced between your devices, though.
3. The browser extension(s) used to lead to duplicate items being saved, though we've made improvements in this regard and I rarely see opportunity for duplicates since the in-line menu. It is possible though that there is still room for further improvement here.

One aspect of this I'd like to see us focus on is the prevention of the creation of duplicate items in the first place. We've made some good changes in this regard as outlined above, but it'd be great to do more. Of course that doesn't help folks that already have duplicates, and I hope we can address that as well. I don't know of anything definite planned at this time, but I will continue to push for a solution.
