Hi Martin, Hi Rado,
Full featured latex output with the possibility to fine touch the
layout computed by graphviz using a graphical tool would be a killer
feature we have been dreaming for long! The trick below is a step in
that direction :-)

Can you give a complete example? With the poset I have tried
(posets.IntegerPartitions(6)), pretty_print always returns None, so
the relabelling above was non functional. On the other hand, using
str(v.element) worked.

You could also do:
sage: H.layout(layout="acyclic", save_pos=True)
sage: graph_editor(H)
Future improvements:
- Display labels in graph_editor
- Handle properly complicated LaTeX labels (the call to layout could
take arguments stating to use the full dot2tex machinery to compute
appropriate bounding boxes for the nodes and edges)
- Make graph_editor available from Sage's text interface. One should
be able to call the java applet from there, no?
- Save back the layout in the original graph being edited, instead of
creating a new graph, in order to not loose information in the process.

Those are used if you check the "live" spring layout.
