I would love a mechanism to be able to add notations or markups to a cloud hosted panorama - it is such a powerful communication tool - adding some lines or circles or text would be super useful
This is a really good idea. Annotations in 360 would be a very compelling reason to use enscape for design review.

Done, thank you!
Just as a quick bump: the below software uses a panorama and lets clients annotate it (which notifies the creator) so that the designer can make changes, then revise and re-upload using the original panorama link… I really don’t want to see Enscape falling behind.
