In the next daily build, we will have interactive label moving, where you 
can pick a label and drag it around, and if you hold down the shift key, 
it will move in Z.  It will default to the Control-button-3 mouse mode, 
but can be reassigned using the mouse mode preferences.  You will also be 
able to change the label offsets using the command line, the "labeloffset 
x y z atom-spec" and "rlabeloffset x y z atom-spec" commands to set the 
offsets and "~labeloffset" and "~rlabeloffset" to reset them to the 
default behavior of adjusting the offset with the representation.

For users with existing saved preferences, you might need to turn label 
dragging on by resetting the mouse mode preferences or by explicitly 
assigning it to Control-button-3.  There's no icon for it yet in the mouse 
modes interface, but it will be the rightmost column for now.

Since the label moving code is new, please send me feedback about how well 
it works for you.
