When I want to check previous versions of my espace then I can go to Open from Environment, select an espace and click on Other Versions. Here I can choose an espace that I want to check and it then opens. However visually there is not much difference between the original and the other version. Sometimes this leads to changing the wrong version. Also when you search for a specific change in the versions it can become confusing which version you already checked.
So therefor I propose to show the version number of the espace so that I clearly see on which version I'm looking.
