@nzdunic You can Undo and Redo an Action (Web) taken in a workspace, and we are currently working on improvements to showcase workspace activity. Is there a specific use case or problem you are trying to solve by reverting to a prior version of a workspace?
P.S. I’ve moved your post into the product feedback category as other Bluescapers may find a feature like this useful. Feel free to add a vote to the topic!
