Version 1.7 makes Genius perfect for my purposes, because I can now see the tiny dots that indicate the vowels for Hebrew without having to switch from 1440 x 900 to 640 x 480 pixels screen resolution when switching from list management to actual drills. Ignoring diacritical marks also makes it possible for me to more easily drill from English to Hebrew, as I haven't bothered to learn how to add the vowels when typing, so just typing the consonants should produce a correct answer as far as Genius is concerned.

I've never bothered to try Genius with Chinese characters (including Japanese words), but I'm sure that the font size options help distinguish between some very similar characters. I'm used to reading copies of copies of faxes from Japan that turn characters into blobs, and I can tell what characters were intended just from the general outline when seeing the words in context, but I'm sure that people who are less familiar with Chinese characters and are using Genius to learn Japanese or Chinese will definitely appreciate the optional larger sized fonts.
