Some feeds, like Slashdot’s, load a story’s comments in feed view. This is annoying me as I only want to see the story but half of my screen is wasted with their top comments.
Being able to inject CSS or JS, based on which feed it is, would be an awesome option!
Yes, this is a great idea. I may try to work something in.
If you only need CSS, the “Stylish” browser plugin can already do this thanks to the beautiful way Newsblur uses URLs! Just install, and go to “Write new style -> for this URL” while reading a story and it will only apply to that feed.
