Hi, I made some improvements in v 0.2 (http://geo.michaelm.free.fr/OpenJUMP/resources/) I added minority, majority, median, and tried to improve the user interface by adding some icons and examples. I also changed its place, putting it in the tools menu, along with the other. I'm still not in hurry to include it, but if you say it's time to do it, I can help. I saw you took much time to fix bugs add plugins, translations and so many improvements. Nice you could add undo to some plugins, I'm sure many users will thank you for this addition (I never used undo capabilities of OJ code, but I have to, I add it on my todo list ;-)
