Provide an option to group a column which is based on an enum by the enum value, but display the DescriptionAttribute or DisplayNameAttribute if existing.
So many times you have sort/group a column by its value like 1,2,3 but display the Description like "Delivery", "Ready", "Pickup". Of course I could add a column to my class which presents the DescriptionAttribute, but then grouping/sorting is wrong: "Delivery", "Pickup", "Ready". It would by much easier if there is an option like "UseDescription". There is something similar with Teleriks "EnumDataSource" which IS using the Description or DisplayName so it should not be that hard to implement the same logic for RadGridView.

Provide option to enable changing the column display index when dragging group cell into the header row.

Currently all of the MoveCurrentTo methods rely on the internal logic of MoveCurrentToPositionCore and users cannot override it through inheritance.
