The feature I’ve found lacking is the ability to copy and paste all the comments on a story into my personal knowledge system and retain the threading and formatting. (I do this every once in a while for threads that have many high quality comments or links that I’d like to save.) I’ve never figured out a way to maintain the threading/indenting.
Can you not just save the html? I tried downloading source then dragging into Apple Notes and it preserved the threading when opened in a browser (using file:///). Local hn hyperlinks failed to resolve but external links are fine. Looks harsh without CSS though.
Firefox has a great feature for taking screenshots and snippets of a webpage. In the settings go to More Tools > Customize Toolbar and drag the Screenshot tool to your toolbar. It's a built-in feature that I use daily.
