Interesting idea!! A while back, I was thinking of making a “hard copy likes/favourites/highlights” feature - where you can select which notes from these lists you’d like to download into your md file in Obsidian. This sounds similar to what you’re asking for?

I could add this to the current plugin! I am trying to keep this plugin low noise, so I’m avoiding bringing too much data like full feeds into the Obsidian workspace if you know what I mean…
