I did not know about PDF Scholar Readee extension [1]. Unfortunately the reason is that I use Firefox only (and safari iOS) and it is not available there. The AI outlines will be useful and I can think of myself using it.
I do not want to comment on number 20. I really wished that I joined CERN 10 years earlier but then it is the mistake of my parents :)
