Thanks heartseed
The more important things that i miss right now is more shaders, like glass shader, water shader, a texture animation shader (i know about the blender workaround but is too much work for something that should be so simple), a robust and easy to use particle system this is one of the things that i really miss, shadows from all lights would also be good, but i can live without it, one also thing i missed when editing this engine was the ability to change textures/materials/sounds on the editor or by LUA coding.
About plugins i don't know anything about C++ to make plugins, is hard enough for me to try learning LUA, ;D .
