A good start but ...

Good:
- the combination of text and sketches and to-dos
- virtually uncomplicated and quick

But not well thought through:
- sketch area is too small
- pictures imported from photo lib cant be rotated
- brush size is not remembered (default size always again)
- eraser size too small and size not remembered (as above)
Hope developers will follow up as I guess this concept has potential.
