Just asking: Is there an open source project that I can self-host that can organize my current subscriptions into separate groups/categories and make things easy to view/hide/digest?

Many moons ago, I could hover and hide a video I didn't want to see in my feed with a single click. Best UX user feature evar... it was gone in a week or two I feel.

I'm kinda ashamed to say I have multiple youtube accounts to keep my sanity, but yeah.
