Hey, my native language has an official count of 44 letters. Heck, if I just count vowels, there's 14 of them ! As nasty as it is, I just dropped the alternate letters and use symbols, otherwise I'd type a message an hour. So, á becomes a', ő is o" and such. Ugly ? Absolutely. But, I'd actually prefer a software solution that automatically transcodes that than getting a super-button-overloaded keyboard. I already hate the way I have to press '8' no less than 6 (yes, six) times on a phone keyboard to get a 'v' letter. My 2c.

As for the layout changes, see attached... You have added é á ó and maybe í (my diacritics are mirrored, sorry), lost some cursors, and probably :;
