I'm wondering what the difference is between for example a collection header, which applies across all headers of all collections but in a unique fashion, compared to when you hack add a section like "image-with-text" that you need to make new section for each of them.
what is the specific code that makes the collection header able to be unique across all the different collection pages - it would be way easier to be able to create a custom section for your custom collection page - but not have to dupe it for each custom collection.
if you know what I mean you know what I mean. If you don't know what I mean I can't help you. here is a gif of a squirrel.
