No, it doesn't. What you can do is use an RSS proxy to create your own feeds of any site and read that through Nextcloud News. I do this for a few specific sites and purposes - e.g. custom searches on auction sites.

As to Nextcloud News being slow with 50K unread items I wonder whether there's something else amiss as I have close to 600K unread items without undue slowdowns.

The only real slowdown I notice in Nextcloud News is caused by a dog-slow piece of javascript in news/templates/part.content.php which causes a delay any time an item is clicked in the feed. This can be solved by removing everything related to 'sharing' (i.o.w. everything after </time> in the list div (class=utils), make sure to balance those tags...). News is much faster in use that way and since I never use the 'sharing' related stuff - if anything needs to be shared I can just share a link instead - nothing of value is lost.

It Technically could as it has plugin support but as far as I am aware it doesn't.

Some alternatives:

- TT-RSS¹ has multiple plugins, including the one I currently support Feediron²

- FressRSS³ has CSS selector support out of the box and has a readability extension⁴ that supports Readability or Mercury

I've been dreaming of porting Feediron to both FreshRSS and Nextcloud news. But I barely have any free time as is... one day
