Good to hear that, I heard his latest formatting changes to the code made it so hard to compare codes, it seems you found a way around that.
If you won't act childish and toxic manner against feedback and ignore them because of personal reasons, it's all good. When you ignore something just because you have personal grudge against the person who reported it, it only affects your users, nobody else. That person just stops using your builds and move on after all.
