Add "published by" column on "Revisions" View

I like your suggestion Martin!
Unfortunately Drupal core doesn't provide a lot of infrastructure to support this. As a programmer it is easy to find out who last modified the content, using existing data structures in code and on the database, but "who flicked the published flag" would require extra infrastructure.

Actually... I you use Revisioning in combination with Workflow you get for each piece of moderated content a history of all the state changes ("in draft", "in review", "published" etc.) that the content went through. With the state changes you get the user name and the time it happened.
That would implement your feature request wouldn't it?
See this tutorial for a step-by-step guide on how to use Revisioning with the Workflow module.

I was wondering whether this could be revisited as a feature to be integrated without Workflow.

I found that I was using Workflow on an installation solely for the purpose of tracking the publisher of a revision. The additional states and such added by workflow were just not helpful for my purposes and just added an unnecessary layer, with the exception of tracking the publisher of revisions.

Would be great to have this option without having to use workflow.

Although useful I won't implement this for 6.x-3.x.
D7 has better infrastructure and I may implement it for Revisioning D7.x

Not adding this to 6.x-3.x branch.
