If I make a box, or a line, or a text comment on a PDF, the next thing I'm likely to want to do is to adjust the shape of or position of the box or line or other thing I've drawn--not make another box! Who makes a box then when they click they make another box, then another, and have to waste time deleting 3 boxes when all they want to do is format the first one they drew. PLEASE have the cursor default back to "select" mode after the user draws something, rather than continuing to keep creating the same shape.
