Yes I did try the “Clip complete Page (HTML)” functionality.
However, the Joplin userstyles will interfere with the resulting HTML:
As you can see there’s the blue in the links, the regular text is in grey (so there’s a low contrast to the white background), there’s a weird blue “Stack Overflow” thingy in-between of the menu on the left side etc.
I tried it with this example (I’m not interested in this particular page, it’s really just an example).
Apart from that, I obviously don’t need or want to have elements like ads, the search, the menu, links like “add a comment”, “start a bounty”, the “The Overflow Blog” ,voting buttons, the recommendations / related links, “Hot Network Questions”, the Footer, the inputs at the bottom etc.
Or to put it differently: the result is full of clutter whereas I only need the essence.
It’s much easier just to use the regular functionality and remove the unneeded stuff from the markdown source, although it is still cumbersome in threads with much content.
The simplified page is varying in it’s quality. It will just take the first answer in this example (not even the question). But I would like to have the other answers as well.
