I needed an open source toolkit / language where i could do some simple animations without having code knowledge or writing my own tools in java etc..I got what exactly i wanted! The ease of use was great and so far everything works well even complex stuff like keyframe interpolations. There are still bugs here and there but nothing too serious yet. If one wants something very easy then this would be perfect since its free software made by people who know whats going on. For me at least simplicity always comes first over features!!
