But it's only Russian so if you are from Bulgaria, Bosnia and Herzegovina, Belarus, Kazakhstan, Kyrgyzstan, Macedonia, Montenegro, Serbia or Ukraine It's won't do you much good.

As I'm from Ukraine I still use the-ebook.org version because they added support for long-presses:

й - symbols from numerical row on keyboard;
ъ - brackets and slashes;
. - punctuation;
а - á, æ | г - ґ, ѓ | е - ё, é | ж - џ, ђ | и - і, ї | к - ќ | л - љ | н - њ | у - ý, ў | ч - ћ | э - є

So it helps, maybe not for everyone but you still can ask them to add some changes.

P.S. Oh and they have arrow keys, because how the hell can you scroll through a long url in a browser to change something in url field? (with standard keyboard it's almost impossible)
