can't you do what you want with

plt.gcf().suptitle('')

after the plot?

matplotlib figures are easy to modify even after they have been displayed

Yes that would certainly be possible, however since many other viz functions already have title or window_title parameters to allow setting the titles, I thought it would be good to have similar support while Dipole plotting as well, for the sake of consistency (and, obviously, usability!)

[agramfort]

ok fair enough. however adding 1s of test for this seems too much. Our test suite is already way to long. Can't you just update a existing test?
