Hovering over the title would give us the latest updated timestamp

Not very sure how the date created will be useful here.

If we do keep this, maybe we can leave out the word Created as all of them only show date created and not last updated. This would help in preventing clutter.

As mentioned in #495 (comment) I'm hesitant to add this feature in the current form.
