Metadata field for a user name - ability to @mention or tie a metadata field to a specific user
Similar to comments or tasks, it would be helpful to be able to autofill and insert a user's name in a metadata field.
There are a lot of use cases here, e.g. establishing the content owner since oftentimes that is different from the folder owner and not easily discernible or searchable.
Current workaround would be to use the text metadata field, which leaves room for user error, typos, or using different variations on people's names. A dropdown list helps with that but isn't a feasible option if you're choosing from a large set of users.
