You can copy and paste to the notes section! When you do, it looks like it hasn't worked as the text is off the left-hand edge of the box, ready for new text to be typed in. Just scroll left to access the pasted text.
The note will be saved with the data file (.psdata) and printed if you do a direct print to your printer but as yet it won't be added to a saved .bmp or .gif graphic file. We will be working on that.
