I was thinking, not all extensions need to be tried to a specific channel experience, and don't always interact with the broadcaster at all. Extensions like the chat translator, or maybe a TTS chat for viewers who can't read well, or visually impared, it would be great to have for users on every channel, not just channels where the broadcaster decides they want to use it. My idea is to have extensions that the view can enable on every channels, and possibly have the panel for viewer extensions be where the chat is, and possibly take up the bottom half of the screen, but same dimensions at chat, so you would have the top half of the screen be the chat, and bottom be the panel, or in a case like the translator, allow the viewer to have the panel take up the full height of chat. then the user can switch between their extensions similar to the experience on the streamer dashboard, and the drop down will be able to cycle through the extensions installed, so you can have multiple extensions running on every channel you visit.
