I use feedly to curate a lot of articles on a variety of topics. I really like the way it displays them for me to review and choose. Something like this would look nice in the LMS when adding an article link.
Doing a quick research, looks like that Moodle has its own block to manage RSS feeds, https://docs.moodle.org/39/en/Remote_RSS_feeds_block, don't know if that can do the trick. The block can be configured to display news from external websites if needed.
BTW we are hiring a new designer for our team. More news about it soon! We are so excited about it.
