I searched around and didn’t find an existing request. There’s a discussion of whether wild/captive observations deserve that status, which will probably be resolved by the addition of a wild/captive filter to the identification page, and a request to change how many IDs (and whose) are necessary for that status, but nothing to rename it to something less confusing.
So I’ve created one. Rename “Research Grade” to “Verified”. Put further discussion of this there.
