Measure-It

[timberzen]

I want to click on the icon and then draw a recangle or line on the screen.
In 2 clicks I can see is something is level or how many px it is out.
I dont want to have to do Alt+P to try and locate a some weird thing on my page.
If I have a web page with slide out panels left or right (mobile use) I dont want the mouse to cause that to happen when doing the measurements, eg try your tool on https://www.enableds.com/products/panomobile/
