Fred Publish/Unpublish per content block, logo change, versioning

I just started using Fred and so far loving it, but have a couple questions.

  1. Is it possible, and if so, how, to make publish and unpublish dates for an individual content block?
  2. Is it possible, and if so, how to change the image of the Open Sidebar icon so I can use our company logo?
  3. Does the versioning add on work with Fred?
