"Youlag Theme for FreshRSS" provides a video-focused browsing experience for your RSS subscriptions. It tries to provide a similar experience to YouTube, primarily through its layout using CSS, but also a little bit of Javascript.
Git repo for more details: https://github.com/civilblur/youlag
In case you're not aware, "FreshRSS is a self-hosted RSS feed aggregator".
The idea is that you subscribe to content creators through YouTube's RSS feed https://www.youtube.com/feeds/videos.xml?channel_id={id_goes_here}, then browse, watch, save to playlist ("label"), right within FreshRSS.
There's also third-party extension for FreshRSS that provides the ability to use Invidious, but as we all know, the public instances are unfortunately struggling quite a bit as of writing.
I think I'll make an extension for this. Would go great with this theme.
Looking forward to it, feel free and share it once it's ready, or if you need any feedback.
