Use "move points", "add points", or "delete points" buttons -- they work for splines as well as polylines.

I'd like to plug the Ipe drawing program: http://ipe.compgeom.org/ I've ditched xfig in favour of ipe for a number of reasons. One of the nice features of ipe is a number of extremely useful "snapping" modes: ever wanted to end a line segment *exactly* on a circle or spline? You can with Ipe! Ipe's "native" file format is either eps or pdf, meaning you never have to remember to "export as eps" after "save file". Ipe is also extensible: you can write a "plugin" so that very specialized operations are available at the click of a button.

Ipe handles latex natively: you type in $\alpha = x + 1$, press CTRL-L, and presto! the rendered text appears on the screen for you to drag around to the proper location. > FWIW, I'm looking now at tgif to see how it does on the curves.
