I have started on this feature:
Data Type Editor will sport at "Tree Sorting" selector where you can choose to sort by a field. You can choose between ascending/descending. You can also choose a 2nd (etc.) field to sort by in case you have duplicates in the primary sort field.
For devs doing data types at code level there will be a new attribute like this:
´[TreeOrderingAttribute(int orderPriority, bool orderDescending)]´
Both will control the sorting in global data folders and page data folders.
No sweet drag/drop or similar interface to manipulate field values yet (still something a user needs to update via edit form or by using the C1Contrib feature mentioned below), but this should take care of the tree rendering, i.e. remove the need for creating a custom Tree Definition.
