I agree with your sentiment and all kudos to the author for being so creativity in creating such tool. I like the idea of having a list of "facts" to keep track of characters in the story.

Even if I won't use it since I dislike using the terminal, I still think its very creative tool for writing.

Strangely I can also understand all the hate but what are you going do? For all those that hate, don't shoot the messenger - the author of the tool is only using those tools that everyone else is also using.

We are collectively going down a very sloppery (pun intended) slope and the author of the tool is just being creativity for their own purposes. Hate the companies pushing this slop down our throats, not those that make use of the existing tools and pushing them to new uses - that's called learning.
