an essential utility for screen design!

This app is simple, clean, and does just what I needed, no more, no less. Measures an area of the screen and then immediately gets out of the way until needed again. The optional zoom window is very helpful for fine tuning.

Two requests to make it even better:.
- when the crosshairs are near the left edge or bottom of the screen, the zoom window can go off screen, which makes it useless! Could it pop to the other side of the crosshairs under these conditions?
- add ability to show physical pixels as well as screen logical points on a Retina display. Some apps size items in one vs the other.
