Dear developers, Ive just bought Byword for my iPad. Its almost perfect when typing in English but when I use Byword for writing the texts in my native Russian its a bit uncomfortable. Russian keyboard on iPad doesnt have , and . and ? and ! marks on the main keyboard layout. There are 33 letters in Russian. You see its a bit more then the number of letters in English. So every time I need to type one of the marks mentioned I have to use additional key _.?123_ to access the mark I need. Pls do one more thing for your product to be the best of all -- add these marks to a swipable row above the keyboard or make it tunable for the best performance. The last would be even better.
Thanks for the good job. Byword is excellent!
