This extension makes tinychat suck just one iota less..
This extension moves the tinychat window above the rest of the page, and makes it become as big as the browser, allowing you to resize the window in any way you desire. When enlarged, cameras have higher detail.
It also moves all of the ads and things below the window so you aren't distracted by them.
In the latest update, it now works across embedded tinychat instances, maximizing the frame it is in and moving it to the top. This requires higher permissions, so anyone updating the application will need to approve them.
