When I mark up my charts for my patients, I like to go over where I'm doing things , how much, and why. The current markup doesn't allow for you to scroll in and out easily. Right now, when I go to zoom in, sometimes it will go back to the chart and then I have to press back in. Also, ability to make the markings smaller, especially for the "dot" markers. I want to be able to fit an entire upper face of marking and still have client be able to clearly see where things will be going. Another thing with the line marker, it wants to do multiple lines in one marking and when I go to stop the line, it will not allow me to drop the end of the line and move on. Now, I currently have to manually draw my straight lines, and they are awful. :) My fault, not yours.
