Show History and Annotate in diff view

[Xarbrough]

In the diff view "Comparing previous content with revisions":

I would like to context-select an item and chose the option "Show History" or "Annotate".

This would make it easier to review changes, because this usually starts in the branch explorer or changesets view, then I double click a changeset to open the diff view and select a file. If the current diff does not answer my question I often would like to check the history of the specific file and see if the offending change was made a couple of changesets earlier for example.
