I initially worried that a brand new name (I went with nootpad) might misleadingly suggest the project was built from scratch rather than being a semi-clean-room re-implementation. Then, I saw that NPP was trademarked and my worries flipped the other direction; the reason I haven't yet published it was because I'm still removing all the NPP references from the source + comments in an abundance of caution, leaving a huge disclaimer/attribution in the README. I know that OSS is an opinionated place and didn't want to step on any toes.
I must say, having all of that anxiety and seeing this guy literally put Don Ho's picture on the website and say that it was being re-named "in collaboration with" Don Ho (i.e. not in response to a legal threat) made me laugh out loud.
