+This collection uses a combination of all these prefixes, and are always sorted in this order:
+
+- CATEGORY:
+  - Ex. "New" collections (010) will always be above "Award" collections (060)
+- LEVEL:
+  - Ex. "+++" will always be above "+", "~~~" will always be below "~", "A" will always be above "B"
+- ALPHABETICAL:
+  - After CATEGORY and LEVEL, collections are sorted alphabetically. If this is undesirable, use CATEGORY and LEVEL to override this default action.
