Finitude - Zen YouTube Subscriptions od engines2k

Finitude allows you to simplify the YouTube subscriptions page, limiting videos shown by recently published and adding the ability to hide the 'Shorts' and 'Most relevant' sections.

This extension, in combination with the built-in option to hide videos from your subscriptions feed, allows you to hit an "inbox zero" by constraining the length of the subscriptions page. In the future it may expand to include features for grouping subscriptions, limiting videos from the same channel, and more.
