Assume you used Views to build a page display (in Drupal 7). So you have the typical "master", and an additional display called (let's say) "MyPageDisplay". And assume that in this "MyPageDisplay" you "overwritten" various settings (fields, sorting, whatever) from your "master".
And then you want to create a block display that's exactly the same (same filters, etc) as the "MyPageDisplay". There doesn't seem to be any facility to copy or clone such "MyPageDisplay"-display.
How can you duplicate a Views display like "MyPageDisplay" as a different display type in D7? And is there any type of improvement in Drupal 8 about this?
