Hi, @fls_admin! First off, welcome to the Bluescape community, and thank you for this feedback.
We’re always seeking ways to improve the product so I will pass along your feedback about timestamped comments to our product team. In the meantime, you can learn more about Commenting on Assets including @ mentioning other collaborators, editing and deleting comments, and more.
