Sort of, but it is not at all discoverable.  

You will notice coordinates on the status bar.  Normally these are the coordinates of the 
mouse cursor.  If you select "Highlight Data Points" on the toolbar, then a marker will 
appear on the curve 'near' the mouse and the status bar coordinates will be of that point 

Now, if you hit 'c', a small cross will appear whereever the active point was, and when you 
now move the mouse, the offset in xy will appear on the status bar as well as the 
coordinates.  'C' clears this mode.

oooh... interesting.  Might be both useful /and/ easy.

Yeah... we really should.  The Ubuntu ppa and the Windows packages (travis build) are 
kept up to date, so you can use those in the mean time (which is why I haven't pushed as 
hard as I could to keep up to date with actual releases.)
