I want UK version update!

I bought Vbookz pdf reader for iPhone, I chose UK version of the reader, and i fell in love with it.
So i decide to buy one for my Mac, and I was disappointed because I could not find any UK accent in it.

For paying 1300 Yen, I expect to have a UK accent update very soon. And I definetely will rate 5 stars intead of 2..

Thanks,
