This is a duplicate of Note attachments panel - sort by date? but it was made when posts in this category were auto-locked after 60 days inactivity.
When I use the Web Clipper browser extension, assets I don't need often come with it. There is no easy way to pinpoint them though. While something like this proposal is ideal, that's going to be a complicated feature. On the other hand, added a Date Created column in the "Note attachments" tool would be a much simpler addition, and it would probably be useful in other situations as well.
