Many times somebody has updated the Publication Properties, Folder Metadata, Structure Group Metadata, Category Properties or Keyword Properties/Metadata only to break something and it be found out later.
We can see the issue, when it occurred, but it would be great if we could see who changed it and get a comparison of the change at least.
We could benefit from complete beginning, although a simpler system would do.
For instance, we could live without rolling back/forward.
I know we can implement our own solutions for this, but it would be good to see this in the core product.
