Interactive sort control in the attribute table

Idea created by duri on Apr 22, 2012
         Display sort direction in the field’s title (e.g. Windows Exlporer) to clearly inform the user about:
    •                the table is sorted,
    •                sorted fields (single/multiple),
    •                sort direction (ascending/descending).

    Sort control improvements:
    •           Provide possibility to sort multiple fields by mouse directly in the table. 
    •           Use single mouse click to sort a field (e.g. Windows Explorer). 
    •           Reset sorting quickly with a mouse shortcut. 
    •           Sort Lock – the table should maintain sort order if new records are added.
