Yeah, it's all done with tables and editing those. Or you can use The Reunion and use the speed up short cuts. I wouldn't say it's hard to understand though... you just enter edit mode, alter the table, and right click save. The saving part with right click makes it fool proof so you dont go editing by accident. I suppose I could always add "press enter" to add the edit from the table.
If not using tables, the GUI etc would be way bigger and all over the place.
