Works well when it works, but it stops showing previews all the time. You hover over the users in your sidebar and everything works fine, then sometime later you try it again and it just doesn't work anymore. Refreshing the page fixes it, but that kind of defeats the purpose of the extension.
There is currently a bug on twitch (unrelated to the extension) where the sidebar items disappear and then re-appear after a few seconds without the extension knowing about it, i would assume twitch would fix it soon. i can look into finding a solution to this for a future version. for now, when it happens you can switch to another tab and switch back for it to work again.
