Kagi News on Android groups news into categories such as Business, Sports, etc., and further by subcategory or tag, for example: Sports > Baseball; however, I do not see a way to group the subcategories, so the news articles present randomly as you scroll through (screenshot).
If it doesn't already exist, a feature to group articles of the same tag or subcategory together would make for a cleaner experience. In this way we could scan all articles about baseball, or football, etc. in one spot easily.
Users can select the subcategories to read, or scroll to them, and see grouped articles of a subcategory they are interested in at a glance.
