Thanks for your reply...I've watched the video, but I need a clone, not an override.
Also I might need to know how to clone other plugin such as cb blog plugin.
Thanks for any help. 
Cloning a plugin is not that easy - you would need to basically redo everything and make sure there are no variable or database conflicts.
Regarding template you sould follow similar approach but no database to worry about.
