Is your feature request related to a problem? Please describe.

Details for bookmarks are as expected, but I was expecting the folders to have additional details apart from who is the owner, like the number of items in the folder(I mention items in order to be inclusive of both nested folders and bookmarks), as well as potentially a creation date, tags, and notes.

**Describe the solution

The report command introduced in 2.1.0 returns the total number of links. This command should be improved to also find and list all duplicate links. There might be valid use cases for having duplicate links, so there should be a flag to disable this feature within report command (e.g. --no-duplicates).
