The next version, which is coming at the end of next week will include support for css sprites for the flag widget. This have advantages in terms of speed and number of requests made to the web server. The code is already active on this site and we would appreciate that you let us know of any issues you encounter on the client side (non standard browsers – IE6, etc.).
Anyone that want to take the code for a spin, is more than welcomed to contact us to get the pre-release code.
