Hi, thanks for this wonderful script, it really helps me a lot.

It seems that the contentSelector for Medium doesn't apply anymore by the time of this comment, could you please take a look into that?

Also, for what it's worth, I'd like to provide a few site settings for some sites I used to browse:

{
"docs.celeryproject.org": {
contentSelector: "[role=main]",
},
"docs.python.org": {
contentSelector: "[role=main]",
},
"packaging.python.org": {
contentSelector: "[role=main]",
},
"readthedocs.io": {
contentSelector: "[role=main]",
},
"www.vinta.com.br": {
contentSelector: ".post-content-body",
},
"ffmpeg.org": {
contentSelector: "#page-content-wrapper",
},
"ruanyifeng.com": {
contentSelector: "[class=hentry]",
},
"realpython.com": {
contentSelector: ".main-content",
},
"en.wikipedia.org": {
contentSelector: "#content",
}
}

Again, really appreciate your work.
