The layout, system, and JLPT levels are superb, and its got me studying Japanese more often.
I only wish the kanji combos were easier to figure out, I mean at first looking at the kanji for katakana, I was wondering if the first kanji was kata or just ka.
So something like putting a dots between the hiraganas to show how each individual kanji in a kanji combination is pronounced, like 片仮名 would be かた•か•な.
