> To Trang:  
> How about naming the UI components as, "menu bar", "variables pane", "area pane", "rendering pane", "layers pane", "actions pane"?. I myself don't like the names very much. Let me know if you have better names.
> "Menu Category"(top-left) instead of "Tabs", "Quick Menu( Button)"(top-right), "Menu Button" will be the names on the "Menu Bar"
