Good tool, hiccup on latest version

Really like this tool. Simple but does what I need. Unfortunately this latest upgrade lost the ability to zoom in on items. It starts with a given magnifcation and lets you zoom out (make things smaller) but you cant zoom in past the default setting. Kind of small for older eyes and when just creating a small number of blocks or graphics. Please fix!
