Keyboard layout switcher, please

For the wishlist:

I18n is a big deal for me 'cuz I'm at least bilingual and it's my job too. So, why doesn't Docky have a keyboard layout switcher, like the Gnome panel does? Using key combinations doesn't work smoothly on my box. And you could do so many cool things with flags. Just please don't do like Gnome and forget to pick default flags. For languages like Spanish that are spoken in lots of countries they show a tacky text abbreviation instead of at least the flag of Spain or whatever country you picked in the menu.
