+=head2 Sorting custom fields applications
+
+Custom fields sorted on multiple layers. First of all custom
+fields with different lookup type are sorted indepedantly. All
+global custom fields have fixed order for all objects, but you
+can insert object specific custom fields between them. Object
+specific custom fields can be applied to several objects and
+be on different place. For example you have GCF1, GCF2, LCF1,
+LCF2 and LCF3 that applies to tickets. You can place GCF2
+above GCF1, but they will be in the same order in all queues.
+However, LCF1 and other local can be placed at any place
+for particular queue: above global, between them or below.
