Fantastic, and practically necessary to wade through modern Youtube. Although, you will have to tweak it in options to get the most out of it. Most people should open the options, and go to the "Overlays" tab and uncheck "Show Overlays". You may also want to go to "Channel", and check off "Add block button next to channel names" for an easy way to block things.

Edit: Looks like youtube is on the warpath again. Much like Channel Blocker and Blocktube before it, the plugin is being supressed by youtube.
