The new beta will use the same file .ini file as the old beta. The .ini file will get things added to it if there are any new settings in the new beta, but all the old stuff will stay as it is. So that part is automatic.

But you will need to copy the FullScreen.js file again for the new beta though, that is separate from the .ini file.
