Draw multiple paths, edit them, then save the whole lot to one XML file. Soon I'll load and reference the paths individually by name in the game itself. Still needs some usability work (like hiding or renaming paths) but nice and functional.
One cool feature is the 'tracers'. These are generic blobs which move along the paths to show how enemies will fly along them. The window in the bottom right has a bunch of sliders to control the trancers' properties like size and rate.
