Is the expectation to show the last build initiator for that workspace, or the first build initiator? Should we only be showing what initiated the build if the workspace is running and not otherwise?

Last. And I'd show it in every case. One way it would be useful is to show that the system auto off is what shut off a workspace.

I am thinking what should the title for this information be. Last initiator, Last built by, Last build by, Initiator, any other suggestions?

Less is more? By
