I really like smart Keyboard pro, I've tried all the keyboards and think that this one is the best.
I use Italian language with T9, I think that this system needs to improve the input of new words.
An Italian word may easily end in different ways depending on the grammar contest in which it is used; e.g.gioc- gioc-are; gioc-oso; gioc-ando; gioc-hino; gioc-hiamo; gioc-ato; gioc-avamo etc
When I tape a new or unknown word, I need to have an option (also in the general setting) which lets me take T9 out and keep the underlined parts of the word in order to save it automatically. So I will be able to write long words more easily.
It might be useful to choose in custom punctuation some arrows to be displayed in the suggestion bar to run over the word.
Best regards,
Francesco
