#1 Randomness and Kana combinations

[Anonymous]

I like the program. It is simple, and it works OK. I have tried many others, and this one simply does what is needed, with little else.

I think it would be improved if two things were changed.

1) The randomness is not very random. I see the same character repeatedly, but other characters not at all. Some sort of weighting system to reduce the likely hood of repeating correctly guessed characters might help this. For example, when you have an incorrect character, you mark it to pop up again, but you could mark correct characters so that the next time they were to come up they would be skipped and another character would be chosen.

2) It would be nice if the yoon kana combinations (kya, kyu, kyo, etc.) were also available.
