I probably will use this tool, but only so I can get a more hands on feel with exactly what each script does. I feel like I could learn better this way. Also, I agree with the people saying that it's good for beginners, but promotes laziness, which is why I say this tool should be a good way to LEARN, not to use this tool and only this tool. Plus, you still have to do some complex stuff when it comes to actually getting it to work in the game, and with the other aspects of a hack.
Still though, I say this tool is a good learning experience for probably the hardest yet most vital part of ROM hacking.
