You can create folders (e.g. based on category) and use them to group similar feeds. Feeds and folders can be arranged with a mouse by using drag & drop. This makes it easy to read e.g. all new feed items in folder "Leadership" (just click the folder).
You can create Rules that are triggered either when a new article arrives (is loaded from the source) or when an article is viewed. Rules can use article title, author and content as an input for rule conditions.
Rule conditions support scanning based on words, text fragment, regular expression and "all", "any", "none" type grouping logic.
Rules can trigger actions such as desktop notification (using Chrome notification system), sound effect, highlighting of the article border, hiding or deleting the article, adding a tag, marking the article as a favorite or highlighting certain words or parts of the content text.
