In my opinion looks don't matter, the hack i am working on doesn't look good at all it is just plain BUT the hacks are working, i am not going to waste my time with looks because the trainer isn't exactly hard to see or use but if you have spare time and you don't mind making it look good then go for it but if you just want working hacks and a plain look then you do that. So basically it is your call, it is not about what other people think it is about how you feel about the hack yourself.
