Found this today, included features that I saw:

• Redirecting from YouTube if the video is also found on PeerTube
• Redirecting to your own instance, when clicking on a video link for a PeerTube video on another instance

Very useful, especially considering you will always get a link to your own instance when using the share function, which isn’t ideal for anyone not on your instance.

If you know any other cool tools and addons for PeerTube, feel free to add them here.
