Most Jenkins jobs produce some kind of artifact, and the publication usually happens in the end of a build. From an artifact deployment/publishing perspective it is hence not very useful to learn when the last job started, or the last duration. Instead, more useful would be the time when that artifact was made available, approximated by the end of the build (start-time + duration).
Usually artifacts are only published on successful builds. Therefore it would be most useful if only stable builds was considered (optionally configurable?).
It would be great if the "extra-columns-plugin" could provide another extra column named "last published", "last deployed", "last finished" or similar, representing when the last (successful) job finished.
Extra points if the name of the column is configurable.
More extra points if the build-status is selectable (last stable, last unstable, last aborted, etc).
