For a lot of release languages the script is obvious, though it is required to specifically select the script each time you select a release language. A little JavaScript function would solve this problem for most users. I know it's possible to use the 'Guess language/script' button but this requires an extra page load and in most cases you still have to manually specify the language. Instead, I'd like to see the script change automatically in case the script is obvious when selecting a specific language (e.g. English -> Latin, Dutch -> Latin, etc.).
