I bought the complete package, and I really liked the jumping animation, it's an essential animation for those of us who want to make platform games.

For now I could suggest a single frame of the run( mario jump pose) or just about any of the current pose frames that you think could work. Like the sample above is using just 3 frame run animation and using the middle frame for the jump.  Adding animations to the current generator is impossible until we develop the whole new version which will take us some time. Hopefully that helps out for now.
