Taking notes through the touch keyboard is not so easy, if you are on the go.
Why not just talking to your phone?
Pin the Voice2Mail tile to the start screen and click it to take a voice note. One more click and this note is saved, by automatically sending it to your email inbox. There you can read your text and hear your voice.
This way you don't have to worry about forgeting important things, while you're on the go.
And of course the app will completely show up in the users selected theme color!
