Freehand Preview Pen Missing
Essentially preview has two pens - the shape pen, if you will, one which has automatic shape detection and will smooth out your shapes and lines after you draw them, and the freehandpen, one which is freehand, and can vary in thickness depending on the pressure applied to a (force) trackpad.
Why do we use the freehand pen? Well, put simply, personally I find that often the shape detection on the shape pen can get in the way of drawing what you intended, and at some point the frustration of having to switch back to the original drawing in the tab that appears on the top right can be annoying and makes you use the freehand.
A few hours ago the freehand tool disappeared. Yesterday I was using it fine, now it is gone.
I've also noticed (though I'm not sure if its always been there) that there is now an ability to make a note on the doc. You can see the disappearance of the pen below (on a PDF doc):
Is this indicative of some preview update which has removed the freehand pen?
How can I get the freehand pen back?
