Improvement: box position on margin

[fayjie92]

Another alternative to your package, 'snaptodo' provides user with an option to raise box. This helps in raising the position of the notes on the margin. Similar option with your package can significantly advance the use cases where a long note gets cropped, due to fix positioning of notes. This is often seen in the bottom part of the page.
