Full list of options for custom collection

Not collections, options for a collection.

From the Wright template index.conf:

{
 "title" : "Index",
 "newTitle": "New Index",
 "folder": true,
 "fullData": true,
 "acceptTypes" : [ "page", "gallery" ],
 "addText": "Add Section",
 "icon": "stacked",
 "index" : true,
 "indexType": "stacked"
}

Tell us about the other five collections you know of.

I'd like to bump this and see if the Squarespace team has any additional documentation on the configuration options?
