For reasons that don't deserve exploration, I would like to view the History of workspaces that have been "Removed" (hidden) because they belonged to a user that is no longer part of our organization. However, that option is not presented when right-clicking on the appropriate workspaces, even with "Show Hidden" items checked.
It should be possible to view the History, which is a read-only operation, without regard to the active/inactive status of a workspace or stream.
