The configure block form UX is a little odd. I think this is an easy thing to fix, but I don't know all of the history here so I am looking for opinions on how to proceed. I have looked at numerous issues about this, but this issue seems different and I think it warrants a new issue:
#1795268: Block metadata should use the standard "name" and "description" fields; follow content type form layout as the model
#202837: Make it easier to customize a block title
#1875260: Make the block title required and allow it to be hidden
#1875252: [META] Make the block plugin UI shippable
#2231551: Clarify block cache settings configuration form
#2089613: Apply machine name ui pattern in the Place Block form
#1925024: Block plugin machine name UX is flawed
#2062715: [META] Many UI/UX issues with custom blocks.
I believe the current form is a bit unclear:
It looks like the corrent title pattern was there in this version: https://drupal.org/node/2089613#comment-8156647 but something happened to it. Separately, it seems that the form would be simpler if the order were as follows: title, items per block, cache settings, region, visibility settings.
