We are porting a contrib module that deals extensively with blocks. As someone that has only ported very simple modules myself, what do I need to know about how Backdrop handles blocks differently than Drupal 7.
I understand that Drupal 7 has a database table for blocks and Backdrop doesn't.
I am pretty sure that custom blocks are stored in config - what about system blocks?
Is there a good section in the docs or api site that will help us?
