YT Bell Manager

YT Bell Manager adds a control panel to YouTube's Subscriptions manager page (youtube.com/feed/channels) so you can manage notification bells across all your subscriptions in one place, instead of visiting each channel individually. Features: • See every subscription's current notification state at a glance (All / Personalized / None) • Search and filter your channel list by name • Change any single channel's notification setting with one click • Bulk-set every filtered channel to All, Personalized, or None at once • Resizable panel that stays out of your way This extension works entirely inside YouTube's own subscriptions page — it doesn't use any private API, collect any data, or communicate with any external server. It simply automates the same clicks you'd make by hand. Not affiliated with YouTube or Google. Completely free.
