Make the body part larger and resize the notesfield.
If you need much more space, make a new layout 'Notes', put only the notes field on this layout and make it as big as you want/need.
Put a button on the first layout to navigate to the 'NoteLayout' and on the noteslayout a button to go back.
Trick can be to make this button dynamic by counting the characters in the notes field.
Once the amount of characters is bigger than a given value, show the button to go to the noteslayout.
But that's up to you...
