It’s good to see they improved it (I think), I used it a few times in the past when I was still learning RxJS and it helped me a bit with some scenarios but I also remember times when it was easier to guess the operator by its name than using this tool :P Not a great fan of tools like this however (“why should I learn the list of operators if there is this tool?” is always behind the corner, and I don’t like that), but for newcomers it could be really useful, thanks for mentioning it! :)
