Mnemonic Annotations, Por Favor – Kanji Flip Review

This is a great app. Knowing the kanji gives you a great leg up on learning to read Japanese. What would be totally awesome, though, would be mnemonic / etymological notes that explain the characters' elements and give tricks for remembering their meanings. Short of that, an annotation feature that would allow you to save your own comments on each character would be helpful.
