Hello.
Thanks for ur suggestion.
I would like to inform you that it is not possible to make a 9th bar , expand inventory ,or adding any kind of "extras" @12xx files (not even on other versions).
I also know every sin has his own combo , and his own way of playing , and I gotta admit ur the first one I know playing with 8 bars

.
Since u said u have a hard time playing sin maybe this topic is helpful :
viewtopic.php?f=115&t=37675(I dont prefer that kind of skill bar - but all sins have different ones)
This video also shows how to use the skills properly in a row , and its a very good skill bar on the following link :

Thanks for understanding.
