Thank to you for #Capyreader!
Have a good day!!!

A personal example: I use it in my Travel folder to stay up to date with sudden discounts and promos from airlines without having to subscribe to all their newsletters.

Nothing special, just content filtering. If word X appears in the title or content of feed/folder Y, then hide, mark or notify it.
A way to collect and prioritize articles, topics, and keywords when there are a lot of feeds.
