 I am using the new symbology editor.
 I have a line vector layer from GRASS  which represents roads and I
 classify them using:
 Categorized
 on a column containing the speed with a colorramp.
 As you can see in the screenshot, QGIS orders the labels random (6 - 15 -
 30 - 65 - 45). 65 should come after 45. So I want to change the order of
 the labels by deleting them and adding them in the right position
 afterwards.
 There is a delete button that deletes any value of the legend, but there
 is no "Add Value" button, so I can not Add any value.

 The same counts for polygon layers.

 Note: The error in the classification seems specific to GRASS (can´t
 repeat it with shapefiles), but the basic point is that It would be nice
 if you could change the order of legend items.   This would be needed when
 classifying on a string field: classify on a text string (like one, two,
 three, for ...), the legend will classify "for - one - three - two". How
 can I change the order these items appear in my legend ...
 Thanks
