We have widened the search modal and added source autocomplete. You no longer need to memorize source names; you can select them from the list to create SourceName: Keyword searches. Reddit is now integrated into a single search using Reddit: Keyword, without distinguishing between subreddits.
Article reactions are categorized into thumbs-up likes and thumbs-down dislikes, and a sort-by-likes option has been added to the home feed. Likes and dislikes cannot be selected simultaneously.
