Too much useless posts from you. All about style deleting... like a broken record. If you don't need styles - not collect them. EZPZ
Okay. I think that's why you're getting resistance. While you may not value the content, it's objectively not useless because in addition to the aesthetic options they provide, they are almost all connected to feats and Skill Points in the game and are therefore functional. Potentially deleting styles opens up possibilities to break those feats and SPs. So, this is unlikely to be considered seriously. Your issue is organization and that can be handled in different ways than deleting the styles from the menu. Suggesting options like improvements on the style menu UI would be better received and supported. Good luck.
Frankly I don’t know what to say to convince you, let us the players manage the content of our inventory seems to me to be an excellent idea.
You can't. I just explained why it's not a good idea -- it has the potential to break important game systems that players need. Focus on your objective; organization. There are other ways to approach a problem. Spend your time on that.
