I frequently forget that specific menu items are in the database and not in the config files. I believe the same is true for taxonomy terms. There is a long discussion about this specifically related to taxonomy in this topic: https://forum.backdropcms.org/forum-topic/config-files-vs-db
I understand that the distinction between what goes in database and what goes into config files is sometimes a little arbitrary. That's fine, but what is the easiest way to track what goes where?
Is there a reference anywhere that makes explicit what information goes into config files and what goes into the database?
