YouTube Sub Hider

Simple extension that hides specified YouTube channels from your subscriptions page.

Maybe a channel has recently filled your feed with videos you aren't interested in. Maybe a channel started posting a video series you aren't interested in, but you want to remain subscribed for future content. This extension let's you toggle a channel's videos from appearing in your subscription feed without unsubscribing from the channel.

Features:
-"Hide" button next to the channel name on each video
-Popup menu that allows you to enter channels to hide manually, toggle whether a hidden channel is enabled, remove channels that have been hidden, and toggle the extension altogether.
-Saves channel data to your browser for persistence between sessions
-Continues hiding specified channels as you scroll through your subscription feed
