I think a useful thing to have in sage would be mutations of graphs (which occur in the theory of cluster algebras by Fomin and Zelevinski). Bernhard Keller has written a java applet (and application) to do this which is widely used.
See here http://people.math.jussieu.fr/~keller/quivermutation/ As far as I know there is no software to do mutations of graphs with potentials (see http://arxiv.org/abs/0704.0649) so this would be very useful to have in sage as well.
