Allow to use of field alias names. These aliases could be used with any export as column headers and in dialogs where the user can select fields, for example in the sort dialog.
This would make Excel exports much better with a proper column header like "Customer ID" instead of any cryptic field name (pk_IDCustomer).
If used in Sort dialog (and other), the end user would be less confused which field to select.
Also, it would be nice if the developer can set an option "[x] Show only fields with alias name", so the end user is not bothered with calculation fields and other system fields.
