Looks like an interesting project. I'm curious if anyone is still active on it?
well, I'm still using I18NEdit regulary in our company. It works quite well, but it has some design flaws (it has been created in a rather hackish way...). To overcome these, large portions of the programs would have to be rewritten - and at least we do not have the manpower to do this currently. Only then it would make sense to start adding new features.
